Cole and Rachel had the same number of mochi balls. After Rachel gave away 17 mochi balls and Cole gave away 55 mochi balls, Rachel had 3 times as many mochi balls as Cole. How many mochi balls did each of them have at first?
| |
Cole |
Rachel |
| Before |
1 u + 55 |
3 u + 17 |
| Change |
- 55 |
- 17 |
| After |
1 u |
3 u |
The number of mochi balls that Cole and Rachel had at first is the same.
3 u + 17 = 1 u + 55
3 u - 1 u = 55 - 17
2 u = 38
1 u = 38 ÷ 2 = 19
Number of mochi balls that each of them had at first
= 1 u + 55
= 19 + 55
= 74
Answer(s): 74
