(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 =
13 Total amount
5x18x1 Remaining amount =
1x53x5 Total amount
58 Remaining amount =
515 Total amount
Amount that Joelle spent on the skirt
= 10 u - 3 u
= 7 u
7 u = 14
1 u = 14 ÷ 7 = 2
Total amount that Joelle spent
= 7 u + 3 u
= 10 u
= 10 x 2
= $20
(b)
Total amount that Joelle had at first
= 15 u
= 15 x 2
= $30
Answer(s): (a) $20; (b) $30
