(a)
Fraction of the remaining amount left
= 1 -
25=
35The amount left is repeated.
Make the numerators the same. LCM of 3 and 1 is 3.
35 Remaining amount =
110 Total amount
3x15x1 Remaining amount =
1x310x3 Total amount
35 Remaining amount =
330 Total amount
Amount that Gabby spent on the dress
= 27 u - 2 u
= 25 u
25 u = 175
1 u = 175 ÷ 25 = 7
Total amount that Gabby spent
= 25 u + 2 u
= 27 u
= 27 x 7
= $189
(b)
Total amount that Gabby had at first
= 30 u
= 30 x 7
= $210
Answer(s): (a) $189; (b) $210
