- Reggie has $71. 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 6 macarons
= 30 ÷ 6
= 5
Cost of 30 macarons
= 5 x 17
= $85
Amount that Winnie needs more to buy the 30 macarons
= 85 - 42.70
= $42.30

Number of sets of 5 macarons that Reggie could buy at Olivia's Bakery
= 71 ÷ 15

Number of macarons that Reggie could buy at Olivia's Bakery
= 4 x 5
= 20
Number of sets of 6 macarons that Reggie could buy at Julie's Bakery
= 71 ÷ 17
= 4 r 3
Number of macarons that Reggie could buy at Julie's Bakery
= 4 x 6
= 24
(More)Greatest possible number of macarons that Reggie can buy with his money = 24
