Jane had some money. If she buys 10 mini cupcakes, she will have $10 left. If she buys 14 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.
10 M + 10 = 14 M + 2
14 M - 10 M = 10 - 2
4 M = 8
1 M = 8 ÷ 4 = 2
Cost of each mini cupcake = $2
(b)
Total amount that Jane had
= 14 x 2 + 2
= 28 + 2
= $30
Answer(s): (a) $2; (b) $30
