5 u |
Change |

|
After |
1 u |
5 u |
(a)
1 u + 59
h = 5 u + 23
h5 u - 1 u = 59
h - 23
h4 u = 59
h - 23
h = 36
h1 u = 36
h ÷ 4 = 9
h Shiyun's amount at first
= 1 u + 59
h = 9
h + 59
h = $68
h (b)
1 u + 5 u = 6 u
6 u = 6 x 9
h = 54
h Amount the two lady had left
= 54 x 37
= $1998
Answer(s): (a) $68
h; (b) $1998
