| Before |
8 u + 88 |
12 u + 80 |
| Change |
- 8 u |
- 12 u |
| After |
$88 |
$80 |
Amount that Risa had left
=
1011 x 88
= $80
The amount that Usha and Risa had at first is the same.
12 u + 80 = 8 u + 88
12 u - 8 u = 88 - 80
4 u = 8
1 u = 8 ÷ 4 = 2
Amount that Usha had at first
= 8 u + 88
= 8 x 2 + 88
= 16 + 88
= $104
Total amount that both girls had at first
= 2 x 104
= $208
Answer(s): $208
