Tammy and Jen had equal amount of money. Each day, Tammy spent $14 and Jen spent $24. When Tammy had $120 left, Jen had
34 as much money left as Tammy. How much money did the two girls have at first?
| |
Tammy |
Jen |
| Before |
14 u + 120 |
24 u + 90 |
| Change |
- 14 u |
- 24 u |
| After |
$120 |
$90 |
Amount that Jen had left
=
34 x 120
= $90
The amount that Tammy and Jen had at first is the same.
24 u + 90 = 14 u + 120
24 u - 14 u = 120 - 90
10 u = 30
1 u = 30 ÷ 10 = 3
Amount that Tammy had at first
= 14 u + 120
= 14 x 3 + 120
= 42 + 120
= $162
Total amount that both girls had at first
= 2 x 162
= $324
Answer(s): $324
