- Shannon has $39.30. She wants to buy 27 croissants from Wendy's Bakery. How much more money does she need to buy the 27 croissants?
- Albert has $82. He wants to buy the greatest possible number of croissants with his money from one of the two shops. What is the greatest possible number of croissants he can buy with his money?
(a)
Number of sets of 9 croissants
= 27 ÷ 9
= 3
Cost of 27 croissants
= 3 x 14
= $42
Amount that Shannon needs more to buy the 27 croissants
= 42 - 39.30
= $2.70
(b)
Number of sets of 8 croissants that Albert could buy at Rachel's Bakery
= 82 ÷ 13
= 6 r 4
Number of croissants that Albert could buy at Rachel's Bakery
= 6 x 8
= 48
(More)Number of sets of 9 croissants that Albert could buy at Wendy's Bakery
= 82 ÷ 14
= 5 r 12
Number of croissants that Albert could buy at Wendy's Bakery
= 5 x 9
= 45
Greatest possible number of croissants that Albert can buy with his money = 48
Answer(s): (a) $2.70; (b) 48
