(a)
Difference in the discount between the pink windbreaker and the red windbreaker
= 25% - 10%
= 15%
Additional amount that Gabby needed to pay if she would buy the pink windbreaker
= 6.10 + 5
= $11.10
15% → 11.10
100% →
11.1015 x 100 = 74
Original price of the pink windbreaker = $74
(b)
Price of the red windbreaker after discount in percentage
= 100% - 25%
= 75%
Price of the red windbreaker after discount
=
75100 x 74
= $55.50
Amount that Gabby had at first
= 55.50 + 5
= $60.50
Answer(s): (a) $74; (b) $60.50
