Audrey had
15 as much money as Isabella at first. After Audrey received $151 and Isabella received $67, both of them had the same amount of money. How much did Isabella have at first?

Audrey |
Isabella |
| Before |
1 u |
5 u |
| Change |
+ 151 |
+ 67 |
| After |
1 u + 151 |
5 u + 67 |
The amount that Audrey and Isabella had in the end is the same.
1 u + 151 = 5 u + 67
5 u - 1 u = 151 - 67 = 84
4 u = 84
1 u = 84 ÷ 4 = 21
Amount that Isabella had at first
= 5 u
= 5 x 21
= $105
Answer(s): $105
