35 of the amount Ethan had left. How much did Ethan have at first?

Total |
| Before |
3 u + 46 |
5 u + 36 |
170 |
| Change |
- 46 |
- 36 |
|
| After |
3 u |
5 u |
|
Amount that Harry had spent
= 46 - 10
= $36
Total amount that Ethan and Harry had at first
= 3 u + 46 + 5 u + 36
= 8 u + 82
8 u + 82 = 170
8 u = 170 - 82
8 u = 88
1 u = 88 ÷ 8 = 11
Amount that Ethan had at first
= 5 u + 46
= 5 x 11 + 46
= 55 + 46
= $101
Answer(s): $101
