(a)
Difference in the discount between the green blazer and the pink blazer
= 20% - 10%
= 10%
Additional amount that Zoe needed to pay if she would buy the green blazer
= 5.40 + 16
= $21.40
10% → 21.40
100% →
21.4010 x 100 = 214
Original price of the green blazer = $214
(b)
Price of the pink blazer after discount in percentage
= 100% - 20%
= 80%
Price of the pink blazer after discount
=
80100 x 214
= $171.20
Amount that Zoe had at first
= 171.20 + 16
= $187.20
Answer(s): (a) $214; (b) $187.20
