(a)
Fraction of the remaining amount left
= 1 -
37=
47The amount left is repeated.
Make the numerators the same. LCM of 4 and 1 is 4.
47 Remaining amount =
17 Total amount
4x17x1 Remaining amount =
1x47x4 Total amount
47 Remaining amount =
428 Total amount
Amount that Yoko spent on the skirt
= 24 u - 3 u
= 21 u
21 u = 336
1 u = 336 ÷ 21 = 16
Total amount that Yoko spent
= 21 u + 3 u
= 24 u
= 24 x 16
= $384
(b)
Total amount that Yoko had at first
= 28 u
= 28 x 16
= $448
Answer(s): (a) $384; (b) $448
