35The amount left is repeated.
Make the numerators the same. LCM of 3 and 1 is 3.
35 Remaining amount =
13 Total amount
3x15x1 Remaining amount =
1x33x3 Total amount
35 Remaining amount =
39 Total amount
Amount that Emily spent on the dress
= 6 u - 2 u
= 4 u
4 u = 68
1 u = 68 ÷ 4 = 17
Total amount that Emily spent
= 4 u + 2 u
= 6 u
= 6 x 17
= $102
(b)
Total amount that Emily had at first
= 9 u
= 9 x 17
= $153
Answer(s): (a) $102; (b) $153
