(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 =
18 Total amount
5x18x1 Remaining amount =
1x58x5 Total amount
58 Remaining amount =
540 Total amount
Amount that Fiona spent on the jumpsuit
= 35 u - 3 u
= 32 u
32 u = 384
1 u = 384 ÷ 32 = 12
Total amount that Fiona spent
= 32 u + 3 u
= 35 u
= 35 x 12
= $420
(b)
Total amount that Fiona had at first
= 40 u
= 40 x 12
= $480
Answer(s): (a) $420; (b) $480
