(a)
Fraction of the remaining amount left
= 1 -
38=
58The amount left is repeated.
Make the numerators the same. LCM of 5 and 1 is 5.
58 Remaining amount =
17 Total amount
5x18x1 Remaining amount =
1x57x5 Total amount
58 Remaining amount =
535 Total amount
Amount that Penelope spent on the jumpsuit
= 30 u - 3 u
= 27 u
27 u = 216
1 u = 216 ÷ 27 = 8
Total amount that Penelope spent
= 27 u + 3 u
= 30 u
= 30 x 8
= $240
(b)
Total amount that Penelope had at first
= 35 u
= 35 x 8
= $280
Answer(s): (a) $240; (b) $280
