- Sarah has $48.50. She wants to buy 20 macarons from Gillian's Bakery. How much more money does she need to buy the 20 macarons?
- Cody has $93. He wants to buy the greatest possible number of macarons with his money from one of the two shops. What is the greatest possible number of macarons he can buy with his money?
(a)
Number of sets of 5 macarons
= 20 ÷ 5
= 4
Cost of 20 macarons
= 4 x 15
= $60
Amount that Sarah needs more to buy the 20 macarons
= 60 - 48.50
= $11.50
(b)
Number of sets of 4 macarons that Cody could buy at Vanessa's Bakery
= 93 ÷ 14
= 6 r 9
Number of macarons that Cody could buy at Vanessa's Bakery
= 6 x 4
= 24
Number of sets of 5 macarons that Cody could buy at Gillian's Bakery
= 93 ÷ 15
= 6 r 3
Number of macarons that Cody could buy at Gillian's Bakery
= 6 x 5
= 30
(More)Greatest possible number of macarons that Cody can buy with his money = 30
Answer(s): (a) $11.50; (b) 30
