(a)
Price to pay for the first item with discount in percent
= 100% - 5%
= 95%
Amount paid for the toy figurine
= 95% x 18
=
95100 x 18
= $17.10
Price to pay for the second item with discount in percent
= 100% - 40%
= 60%
Amount paid for the lego set
= 60% x 15
=
60100 x 15
= $9.00
Total amount paid for the two items
= 17.10 + 9.00
= $26.10
(b)
Total discount in percent
= 5% + 40%
= 45%
45% of the price = 11.25
1% of the price = 11.25 ÷ 45 = 0.25
100% of the price = 100 x 0.25 = 25
Price of each mini plane = $25
Answer(s): (a) $26.10; (b) $25
