Lily had
15 as much money as Sophia at first. After Lily received $316 and Sophia received $80, both of them had the same amount of money. How much did Sophia have at first?

Lily |
Sophia |
| Before |
1 u |
5 u |
| Change |
+ 316 |
+ 80 |
| After |
1 u + 316 |
5 u + 80 |
The amount that Lily and Sophia had in the end is the same.
1 u + 316 = 5 u + 80
5 u - 1 u = 316 - 80 = 236
4 u = 236
1 u = 236 ÷ 4 = 59
Amount that Sophia had at first
= 5 u
= 5 x 59
= $295
Answer(s): $295
