Fanny had some money. If she buys 11 mochi balls, she will have $7 left. If she buys 14 mochi balls, she will have $1 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.
11 M + 7 = 14 M + 1
14 M - 11 M = 7 - 1
3 M = 6
1 M = 6 ÷ 3 = 2
Cost of each mochi ball = $2
(b)
Total amount that Fanny had
= 14 x 2 + 1
= 28 + 1
= $29
Answer(s): (a) $2; (b) $29
