15 as much money as Tommy at first. After Audrey received $317 and Tommy received $77, both of them had the same amount of money. How much did Tommy have at first?

Audrey |
Tommy |
| Before |
1 u |
5 u |
| Change |
+ 317 |
+ 77 |
| After |
1 u + 317 |
5 u + 77 |
The amount that Audrey and Tommy had in the end is the same.
1 u + 317 = 5 u + 77
5 u - 1 u = 317 - 77 = 240
4 u = 240
1 u = 240 ÷ 4 = 60
Amount that Tommy had at first
= 5 u
= 5 x 60
= $300
Answer(s): $300
