(a)
Fraction of the remaining amount left
= 1 -
58=
38The amount left is repeated.
Make the numerators the same. LCM of 3 and 1 is 3.
38 Remaining amount =
14 Total amount
3x18x1 Remaining amount =
1x34x3 Total amount
38 Remaining amount =
312 Total amount
Amount that Jean spent on the shirt
= 9 u - 5 u
= 4 u
4 u = 28
1 u = 28 ÷ 4 = 7
Total amount that Jean spent
= 4 u + 5 u
= 9 u
= 9 x 7
= $63
(b)
Total amount that Jean had at first
= 12 u
= 12 x 7
= $84
Answer(s): (a) $63; (b) $84
