(a)
Fraction of the remaining amount left
= 1 -
47=
37The amount left is repeated.
Make the numerators the same. LCM of 3 and 1 is 3.
37 Remaining amount =
14 Total amount
3x17x1 Remaining amount =
1x34x3 Total amount
37 Remaining amount =
312 Total amount
Amount that Gabby spent on the shirt
= 9 u - 4 u
= 5 u
5 u = 75
1 u = 75 ÷ 5 = 15
Total amount that Gabby spent
= 5 u + 4 u
= 9 u
= 9 x 15
= $135
(b)
Total amount that Gabby had at first
= 12 u
= 12 x 15
= $180
Answer(s): (a) $135; (b) $180
