20 shower heads If the price of a toilet is three times the price of a shower head, what percent of the total cost was the cost of all the shower heads? 9%

10%

11%

13%

Explanation of Answer:

To solve this, you can

place values for the

toilets and shower

heads If you apply $3

for each toilet and $1 for

each shower head, your

total cost will be $200

Of this, $20 or 10% is

spent on shower heads.

10) A car averages 55 mph for the first 4 hours of a trip and averages 70 mph for each additional hour The average speed for the entire trip was

60 mph How many hours long is the trip?

6 8 11 12 14

Start with the equation (55(4) + 70x) / 4+x = 60

= (220 + 70x) / 4+x = 60

Trang 6

Multiply both sides by 4+x

220 + 70x = 240 + 60x

Which gives you

10x = 20, so x = 2 Add this to the 4 hours and you

have 6

tickets sold, then 60 - s =:

You know that sales s * 1.25 = 60.

Therefore s = 60 / 1.25 or s = 48.

60 - 48 = 12

17) How many integers between 100 and 150, inclusive, cannot be evenly divided by 3 nor 5?

35

27

25

26

28

The numbers that are divisible by 3 or 5 between 100 and 150 inclusive are:

100, 102, 105, 108, 110, 111, 114, 115, 117, 120, 123, 125, 126, 129, 130, 132, 135, 138,

140, 141, 144, 145, 147 and 150

These are 24 The total numbers between 100 and 150 (inclusive) is 51

Thus, the answer is 51 - 24 which is 27

18) Susan wants to put up fencing around three sides of her rectangular yard and leave a side of 20 feet unfenced If the yard has an area of 680 square feet, how many feet of fencing does she need?

38

88

97

Trang 10

The area of the yard is 20w= 680 square feet, so w = 680/ 20 = 34 feet The length of the fencing needed is 34+20+34=88 feet

19) Which of the following equations has a root in common with x2 - 6x + 5 = 0?

x2 + 1 = 0

x2 - x - 2 = 0

2x2 - 2 = 0

x2 - 2x - 3 = 0

x2 - 10x - 5 = 0

20) A computer store regularly sells all stock at a discount of 20 percent to 40 percent If

an additional 25 percent were deducted from the discount price during a special sale, what would be the lowest possible price of a part costing $16 before any discount?

$6.80

$7.20

$9.60

$11.30

$14.80

The lowest possible price is paid when the maximum discount is received, so the lowest possible regular price is $16 - 0.40($16) = $9.60 With an additional 25 percent discount, the lowest possible price is $9.60 - 0.25($9.60) = $7.20 The best answer is the second

one

Alternatively, the lowest possible price to be paid for the item can be calculated by

realizing that if you are being given a discount of 40 percent you are paying 60 percent of the listed price of the item If an additional 25 percent discount is offered on the item, the price of the item becomes (0.75)(0.60)($16) = $7.20

21) If "basis points" are defined so that 1 percent is equal to 100 basis points, then 75.5

percent is how many basis points greater than 65.5 percent?

.01

Trang 11

10

100

1000

There is a difference of 10 percent between 75.5 percent and 65.5 percent If 1 percent equals 100 basis points, then 10 percent equals 10(100) or 1,000 basis points

22) If x + 8y = 20 and x = -3y, then y =

3

4

5

6

8

Substitution of the second equation into the first equation yields

(-3y) + 8y = 20

5y = 20

y = 4

23) If 2x + y = 10 and x = 3, what is x - y

-3

-1

0

1

3

Since x = 3, 2x + y = 6 so 6 + y = 10 resulting in y = 4 Therefore x - y = 3 - 4 = (-1)

24) If a triangle has a base B and the altitude of the triangle is twice the base, then the area

of the triangle is

.5AB

Trang 12

.5AB2

B2

2B2

The area of a triangle is 5 the base times the altitude The altitude is 2B so the area is B2 25) If y/x = 1/3 and x + 2y = 10, then x is

2

3

4

5

6

Since y/x = 1/3, cross multiply to obtain x = 3y Substitute x = 3y into x + 2y = 10 to get 3y + 2y = 5y = 10 Therefore y =2 and x = 6

26) The sum of 5 consecutive integers is 35 How many of the five consecutive integers are prime numbers?

0

1

The "middle number" should be near 7 because 35/5 = 7 Since 5 + 6 + 7 + 8 + 9 = 35, 5 and 7 are prime numbers You may think this is a trick question, but it can appear on the exam

27) Which of the following inequalities is the solution to the inequality

7x - 5 < 2x + 18?

x < 13/5

x > 23/9

x < 23/9

x > 23/5

x < 23/5

Trang 13

Use the properties of inequalities to solve the given inequality Subtract 2x from each side

to get 5x - 5 < 18 Next add 5 to each side to obtain 5x < 23 Finally divide each side by 5

to get x < 23/5

28) Apples cost $x a bag for the first 100 bags a store buys from a wholesaler All bags

bought in addition to the first 100 get a discount of 10% How much does it cost to buy

150 bags of apples from the wholesaler?

$100

$140x

$145x

$150x

$100x + $50

Since the first 100 bags cost $x each, the total cost of the first 100 bags is $100x Since the remaining 50 bags are discounted 10%, each bag costs 90% of $x or $(.90)x and the 50

bags cost $45x The total cost is $145x

30) John weighs twice as much as Susan Susan's weight is 60% of Sam's weight Mark

weighs 50% of Lynn's weight Lynn weighs 190% of John's weight Which of these 5 people weighs the least?

John

Susan

Sam

Trang 14

Lynn

John weighs twice as much as Susan, so John cannot weigh the least Susan's weight is

less than Sam's, so Sam's weight is not the least Mark's weight is 1/2 of Lynn's weight so Lynn can't weigh the least The only possible answers are Susan or Mark Let J, S, Sa, M,

L stand for the weights M = 5L = 5(1.9)J So M = 95J Since J = 2S, we know S = 5J, therefore Susan weighs the least
