Rael had $57 more than Abi. After Abi spent
29 of her money, Rael had four times as much money as Abi. How much money did Rael have at first?
| |
Rael |
Abi |
| Before |
28 u |
9 u |
| Change |
|
- 2 u |
| After |
28 u |
7 u |
Amount that Rael had in the end
= 4 x 7 u
= 28 u
If Abi had another $57 at first, the amounts that Rael and Abi each had at first will be the same.
28 u = 9 u + 57
28 u - 9 u = 57
19 u = 57
1 u = 57 ÷ 19 = 3
Amount Rael had at first
= 28 u
= 28 x 3
= $84
Answer(s): $84
