Fraction of the remaining amount left
= 1 -

58The amount left is repeated.
Make the numerators the same. LCM of 5 and 1 is 5.
58 Remaining amount =
110 Total amount
5x18x1 Remaining amount =
1x510x5 Total amount
58 Remaining amount =
550 Total amount
Amount that Kylie spent on the jumpsuit
= 45 u - 3 u
= 42 u
42 u = 630
1 u = 630 ÷ 42 = 15
Total amount that Kylie spent
= 42 u + 3 u
= 45 u
= 45 x 15
= $675
(b)
Total amount that Kylie had at first
= 50 u
= 50 x 15
= $750
Answer(s): (a) $675; (b) $750
