Xandra had some money. If she buys 4 mochi balls, she will have $10 left. If she buys 6 mochi balls, she will have $2 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.
4 M + 10 = 6 M + 2
6 M - 4 M = 10 - 2
2 M = 8
1 M = 8 ÷ 2 = 4
Cost of each mochi ball = $4
(b)
Total amount that Xandra had
= 6 x 4 + 2
= 24 + 2
= $26
Answer(s): (a) $4; (b) $26
