(27 x 6) + Question #15 Marissa is saving money to buy an I-phone that costs $299 In the last weeks, she has earned $54 a.) Write an equation that you could use to determine how much money, m, she earns per week Then solve your answer b.) How many more weeks does Marissa have to work to have enough money to buy the Iphone? a.) $54 ÷ = m $54 ÷ = $9 per week b.) $299 - $54 = $245 left to save $245 ÷ $9 = 27 R2 After 27 weeks, Marissa will only have saved $243 She needs an additional week in order to get the remaining $2 she needs Answer: 28 Weeks Question #16 Tim Horton’s sells an average of 570 cups of coffee a day The manager wants to be sure he has enough carry-out containers on hand Each carry-out container holds cups of coffee If the manager expects half of all the coffee sold to be put in carry-out containers, how many will he need for that day? 570 cups sold ÷ (half) = 285 cups to go into carry out containers 570 ÷ = 285 285 ÷ cups per container = 71 R 71 containers are not enough cup of coffee will not have a carry-out container Therefore, the manager needs to have 72 carry out containers on hand There will be extra spaces in the 72nd container Answer: 72 carry out containers Question #17 The cafeteria ordered 2,000 freezie pops for the school picnic The freezie pops were shipped in cardboard boxes that held freezies Any freezies left after the cardboard boxes were packed, were sent in an insulated bag How many freezies were shipped in an insulated bag? 2000 freezies ÷ per box = 285 R5 285 boxes of freezies were shipped The remaining were sent in an insulated bag Answer: sent in an insulated bag ... (3 times as many brownies) = 135 cookies 45 brownies + 135 cookies = 180 goodies 180 goodies ÷ items per plate = 22 R4 items Answer: 23 plates Question #10 A case of school supplies holds 2 63. .. swam after weeks? 2824 laps ÷ weeks = 706 laps per week 706 laps per week x weeks = 635 4 total laps Answer: 635 4 laps Question #6 Mrs Witt is planting new flower gardens She would like to have...
