(a)
Fraction of the remaining amount left
= 1 -

35The amount left is repeated.
Make the numerators the same. LCM of 3 and 1 is 3.
35 Remaining amount =
15 Total amount
3x15x1 Remaining amount =
1x35x3 Total amount
35 Remaining amount =
315 Total amount
Amount that Jade spent on the blazer
= 12 u - 2 u
= 10 u
10 u = 190
1 u = 190 ÷ 10 = 19
Total amount that Jade spent
= 10 u + 2 u
= 12 u
= 12 x 19
= $228
(b)
Total amount that Jade had at first
= 15 u
= 15 x 19
= $285
Answer(s): (a) $228; (b) $285
