Min had some money. If she buys 9 mini cupcakes, she will have $8 left. If she buys 12 mini cupcakes, she will have $2 left.
- How much does each mini cupcake cost?
- How much money does she have?
(a)
Let 1 M be the price of 1 mini cupcake.
9 M + 8 = 12 M + 2
12 M - 9 M = 8 - 2
3 M = 6
1 M = 6 ÷ 3 = 2
Cost of each mini cupcake = $2
(b)
Total amount that Min had
= 12 x 2 + 2
= 24 + 2
= $26
Answer(s): (a) $2; (b) $26
