Total |
| Before |
8 u |
4 p |
$28 |
| Change |
- 5 u |
- 3 p |
|
| After |
3 u |
1 p |
$27 |
8 u + 4 p = 28 --- (1)
3 u + 1 p = 27 --- (2)
(2) x 4 12 u + 4 p = 108 --- (3)
(3) - (1)
12 u - 8 u = 108 - 28
4 u = 80
1 u = 80 ÷ 4 = 20
Amount that Pamela had at first
= 8 u
= 8 x 20
= $160
Answer(s): $160
