Question

Ms. Geronimo has a $10 gift certificate to her local bakery.

a. If she buys a slice of pie for $2.20 and uses the rest of the gift certificate to buy chocolate macaroons that cost $0.60 each, how many macaroons can Ms. Geronimo buy?
b. If she changes her mind and instead buys a loaf of bread for $4.60 and uses the rest to buy cookies that cost 1 1/2 times as much as the macaroons, how many cookies can she buy?

Answer 1

Answer: a) 13 macaroons

b) 6 cookies

Step-by-step explanation: Total = $10

a) $2.20/slice of pie

$0.60/macaroon

10 - 2.20 = 7.80

7.80/0.6 = 13

b) $4.60/loaf

cookies = 1 1/2*macaroons = (1 + 0.5)*0.6 = 1,5 * 0.6 = 0.90

cookies = $0.90

10 - 4.60 = 5.40

5.40/0.9 = 6
