Difference in the discount between the grey jumpsuit and the red jumpsuit
= 35% - 20%
= 15%
Additional amount that Vanessa needed to pay if she would buy the grey jumpsuit
= 9.10 + 17
= $26.10
15% → 26.10
100% →
26.1015 x 100 = 174
Original price of the grey jumpsuit = $174
(b)
Price of the red jumpsuit after discount in percentage
= 100% - 35%
= 65%
Price of the red jumpsuit after discount
=
65100 x 174
= $113.10
Amount that Vanessa had at first
= 113.10 + 17
= $130.10
