Jade and Joelle had the same amount of money at first. After Jade gave $240 to her son, Joelle had 7 times as much money as Jade. How much did Jade have in the end?

Jade |
Joelle |
| Before |
1x7 =
7 u |
1x7 =
7 u |
| Change |
- $240 |
|
| After |
1 u |
7 u |
The amount that Joelle had at first and in the end remains unchanged. Make the amount that Joelle had the same. LCM of 1 and 7 is 7.
Amount that Jade gave to her son
= 7 u - 1 u
= 6 u
6 u = 240
1 u = 240 ÷ 6 = 40
Amount that Jade had in the end
= 1 u
= $240
Answer(s): $240
