1 u + $56g |
3 u |
Change |

After |
1 u |
3 u |
(a)
1 u + 56
g = 3 u + 25
g3 u - 1 u = 56
g - 25
g2 u = 56
g - 25
g = 31
g1 u = 31
g ÷ 2 = 15.5
g Cindy's amount at first
= 1 u + 56
g = 15.5
g + 56
g = $71.5
g (b)
1 u + 3 u = 4 u
4 u = 4 x 15.5
g = 62
g Amount the two women had left
= 62 x 26
= $1612
Answer(s): (a) $71.5
g; (b) $1612
