1 u + $74h |
4 u |
Change |
- $74h |
|
After |
1 u |
4 u |
(a)
1 u + 74
h = 4 u + 26
h4 u - 1 u = 74
h - 26
h3 u = 74
h - 26
h = 48
h1 u = 48
h ÷ 3 = 16
h Pamela's amount at first
= 1 u + 74
h = 16
h + 74
h = $90
h (b)
1 u + 4 u = 5 u
5 u = 5 x 16
h = 80
h Amount the two women had left
= 80 x 26
= $2080
Answer(s): (a) $90
h; (b) $2080
