(a)
Fraction of the remaining amount left
= 1 -

37The amount left is repeated.
Make the numerators the same. LCM of 3 and 1 is 3.
37 Remaining amount =
17 Total amount
3x17x1 Remaining amount =
1x37x3 Total amount
37 Remaining amount =
321 Total amount
Amount that Pamela spent on the dress
= 18 u - 4 u
= 14 u
14 u = 140
1 u = 140 ÷ 14 = 10
Total amount that Pamela spent
= 14 u + 4 u
= 18 u
= 18 x 10
= $180
(b)
Total amount that Pamela had at first
= 21 u
= 21 x 10
= $210
Answer(s): (a) $180; (b) $210
