25The amount left is repeated.
Make the numerators the same. LCM of 2 and 1 is 2.
25 Remaining amount =
18 Total amount
2x15x1 Remaining amount =
1x28x2 Total amount
25 Remaining amount =
216 Total amount
Amount that Nora spent on the dress
= 14 u - 3 u
= 11 u
11 u = 88
1 u = 88 ÷ 11 = 8
Total amount that Nora spent
= 11 u + 3 u
= 14 u
= 14 x 8
= $112
(b)
Total amount that Nora had at first
= 16 u
= 16 x 8
= $128
Answer(s): (a) $112; (b) $128
