Gabby had some money. If she buys 8 mochi balls, she will have $10 left. If she buys 11 mochi balls, she will have $4 left.
- How much does each mochi ball cost?
- How much money does she have?
(a)
Let 1 M be the price of 1 mochi ball.
8 M + 10 = 11 M + 4
11 M - 8 M = 10 - 4
3 M = 6
1 M = 6 ÷ 3 = 2
Cost of each mochi ball = $2
(b)
Total amount that Gabby had
= 11 x 2 + 4
= 22 + 4
= $26
Answer(s): (a) $2; (b) $26
