- Raeann has $26.80. She wants to buy 27 macarons from Jaslyn's Bakery. How much more money does she need to buy the 27 macarons?
- Fabian has $61. 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 9 macarons
= 27 ÷ 9
= 3
Cost of 27 macarons
= 3 x 15
= $45
Amount that Raeann needs more to buy the 27 macarons
= 45 - 26.80
= $18.20
(b)
Number of sets of 8 macarons that Fabian could buy at Yen's Bakery
= 61 ÷ 12
= 5 r 1
Number of macarons that Fabian could buy at Yen's Bakery
= 5 x 8
= 40
(More)Number of sets of 9 macarons that Fabian could buy at Jaslyn's Bakery
= 61 ÷ 15
= 4 r 1
Number of macarons that Fabian could buy at Jaslyn's Bakery
= 4 x 9
= 36
Greatest possible number of macarons that Fabian can buy with his money = 40
Answer(s): (a) $18.20; (b) 40
