(a)
Fraction of the remaining amount left
= 1 -
710=
310The amount left is repeated.
Make the numerators the same. LCM of 3 and 1 is 3.
310 Remaining amount =
19 Total amount
3x110x1 Remaining amount =
1x39x3 Total amount
310 Remaining amount =
327 Total amount
Amount that Abi spent on the windbreaker
= 24 u - 7 u
= 17 u
17 u = 289
1 u = 289 ÷ 17 = 17
Total amount that Abi spent
= 17 u + 7 u
= 24 u
= 24 x 17
= $408
(b)
Total amount that Abi had at first
= 27 u
= 27 x 17
= $459
Answer(s): (a) $408; (b) $459
