Riordan had 5 times as much money as Bryan. After Bryan's father gave Bryan $37, the amount of money Riordan had become $5 less than that of Bryan's. How much did Bryan have in the end?

| Before |
1 u |
5 u |
| Change |
+ $37 |
|
| After |
1 u + $37 |
5 u |
The amount that Riordan had remains unchanged.
If Riordan had another $5, Bryan and Riordan would have the same amount in the end.
5 u + 5 = 1 u + 37
5 u - 1 u = 37 - 5
4 u = 37 - 5
4 u = 32
1 u = 32 ÷ 4 = 8
Amount that Bryan had in the end
= 1 u + 37
= 8 + 37
= $45
Answer(s): $45
