(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 =
15 Total amount
5x18x1 Remaining amount =
1x55x5 Total amount
58 Remaining amount =
525 Total amount
Amount that Eva spent on the shirt
= 20 u - 3 u
= 17 u
17 u = 289
1 u = 289 ÷ 17 = 17
Total amount that Eva spent
= 17 u + 3 u
= 20 u
= 20 x 17
= $340
(b)
Total amount that Eva had at first
= 25 u
= 25 x 17
= $425
Answer(s): (a) $340; (b) $425
