Vaidev had $60 more than Penelope. After Penelope spent
13 of her money, Vaidev had four times as much money as Penelope. How much money did Vaidev have at first?
| |
Vaidev |
Penelope |
| Before |
8 u |
3 u |
| Change |
|
- 1 u |
| After |
8 u |
2 u |
Amount that Vaidev had in the end
= 4 x 2 u
= 8 u
If Penelope had another $60 at first, the amounts that Vaidev and Penelope each had at first will be the same.
8 u = 3 u + 60
8 u - 3 u = 60
5 u = 60
1 u = 60 ÷ 5 = 12
Amount Vaidev had at first
= 8 u
= 8 x 12
= $96
Answer(s): $96
