35% =
35100 =
720Number of kiwis = 7 u
Number of guavas = 20 u - 7 u = 13 u
Price of each kiwi in percent = 100%
Price of each guava in percent = 100% + 50% = 150%
Price of each guava
= 1.20 x 150%
= 1.20 x
150100 = $1.80
8.4 u + 23.4 u = 477
31.8 u = 477
1 u = 477 ÷ 31.8 = 15
Cost of the kiwis
= 7 u x 1.20
= 7 x 15 x 1.20
= $126
(b)
Number of guavas ordered
= 13 u
= 13 x 15
= 195
Answer(s): (a) $126; (b) 195
