Nicole and Jane had equal amount of money. Each day, Nicole spent $18 and Jane spent $20. When Nicole had $112 left, Jane had
12 as much money left as Nicole. How much money did the two girls have at first?
| |
Nicole |
Jane |
| Before |
18 u + 112 |
20 u + 56 |
| Change |
- 18 u |
- 20 u |
| After |
$112 |
$56 |
Amount that Jane had left
=
12 x 112
= $56
The amount that Nicole and Jane had at first is the same.
20 u + 56 = 18 u + 112
20 u - 18 u = 112 - 56
2 u = 56
1 u = 56 ÷ 2 = 28
Amount that Nicole had at first
= 18 u + 112
= 18 x 28 + 112
= 504 + 112
= $616
Total amount that both girls had at first
= 2 x 616
= $1232
Answer(s): $1232
