Charlie and Fabian had an equal number of mochi balls at first. Charlie and Fabian ate 20 and 8 mochi balls respectively. In the end, Fabian has five times as many mochi balls as Charlie. How many mochi balls did each of them has at first?
| |
Charlie |
Fabian |
| Before |
1 u + 20 |
5 u + 8 |
| Change |
- 20 |
- 8 |
| After |
1 u |
5 u |
Charlie and Fabian had an equal number of mochi balls at first.
5 u + 8 = 1 u + 20
5 u - 1 u = 20 - 8
4 u = 12
1 u = 12 ÷ 4 = 3
Number of mochi balls that each of them had at first
= 1 u + 20
= 3 + 20
= 23
Answer(s): 23
