(a)
Price to pay for the first item with discount in percent
= 100% - 5%
= 95%
Amount paid for the mini-helicopter
= 95% x 18
=
95100 x 18
= $17.10
Price to pay for the second item with discount in percent
= 100% - 30%
= 70%
Amount paid for the flying saucer
= 70% x 10
=
70100 x 10
= $7.00
Total amount paid for the two items
= 17.10 + 7.00
= $24.10
(b)
Total discount in percent
= 5% + 30%
= 35%
35% of the price = 10.85
1% of the price = 10.85 ÷ 35 = 0.31
100% of the price = 100 x 0.31 = 31
Price of each kitchen set = $31
Answer(s): (a) $24.10; (b) $31
