(a)
Price to pay for the first item with discount in percent
= 100% - 10%
= 90%
Amount paid for the basketball set
= 90% x 18
=
90100 x 18
= $16.20
Price to pay for the second item with discount in percent
= 100% - 25%
= 75%
Amount paid for the doll set
= 75% x 10
=
75100 x 10
= $7.50
Total amount paid for the two items
= 16.20 + 7.50
= $23.70
(b)
Total discount in percent
= 10% + 25%
= 35%
35% of the price = 10.15
1% of the price = 10.15 ÷ 35 = 0.29
100% of the price = 100 x 0.29 = 29
Price of each frisbee = $29
Answer(s): (a) $23.70; (b) $29
