Tiffany |
| Before |
5 u + 88 |
9 u + 8 |
| Change |
- 5 u |
- 9 u |
| After |
$88 |
$8 |
Amount that Tiffany had left
=
111 x 88
= $8
The amount that Ivory and Tiffany had at first is the same.
9 u + 8 = 5 u + 88
9 u - 5 u = 88 - 8
4 u = 80
1 u = 80 ÷ 4 = 20
Amount that Ivory had at first
= 5 u + 88
= 5 x 20 + 88
= 100 + 88
= $188
Total amount that both girls had at first
= 2 x 188
= $376
Answer(s): $376
