Avery had
15 as much money as Noah at first. After Avery received $200 and Noah received $84, both of them had the same amount of money. How much did Noah have at first?

Avery |
Noah |
Before |
1 u |
5 u |
Change |
+ 200 |
+ 84 |
After |
1 u + 200 |
5 u + 84 |
The amount that Avery and Noah had in the end is the same.
1 u + 200 = 5 u + 84
5 u - 1 u = 200 - 84 = 116
4 u = 116
1 u = 116 ÷ 4 = 29
Amount that Noah had at first
= 5 u
= 5 x 29
= $145
Answer(s): $145
