Archie had $56 more than Wendy. After Wendy spent
15 of her money, Archie had thrice as much money as Wendy. How much money did Archie have at first?
| |
Archie |
Wendy |
| Before |
12 u |
5 u |
| Change |
|
- 1 u |
| After |
12 u |
4 u |
Amount that Archie had in the end
= 3 x 4 u
= 12 u
If Wendy had another $56 at first, the amounts that Archie and Wendy each had at first will be the same.
12 u = 5 u + 56
12 u - 5 u = 56
7 u = 56
1 u = 56 ÷ 7 = 8
Amount Archie had at first
= 12 u
= 12 x 8
= $96
Answer(s): $96
