Natalie had some money. If she buys 6 mini cupcakes, she will have $9 left. If she buys 8 mini cupcakes, she will have $1 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.
6 M + 9 = 8 M + 1
8 M - 6 M = 9 - 1
2 M = 8
1 M = 8 ÷ 2 = 4
Cost of each mini cupcake = $4
(b)
Total amount that Natalie had
= 8 x 4 + 1
= 32 + 1
= $33
Answer(s): (a) $4; (b) $33
