Archie had $60 more than Penelope. After Penelope spent
23 of her money, Archie had five times as much money as Penelope. How much money did Archie have at first?
| |
Archie |
Penelope |
| Before |
5 u |
3 u |
| Change |
|
- 2 u |
| After |
5 u |
1 u |
Amount that Archie had in the end
= 5 x 1 u
= 5 u
If Penelope had another $60 at first, the amounts that Archie and Penelope each had at first will be the same.
5 u = 3 u + 60
5 u - 3 u = 60
2 u = 60
1 u = 60 ÷ 2 = 30
Amount Archie had at first
= 5 u
= 5 x 30
= $150
Answer(s): $150
