14Number of kiwis = 1 u
Number of mangoes = 4 u - 1 u = 3 u
Price of each kiwi in percent = 100%
Price of each mango in percent = 100% + 50% = 150%
Price of each mango
= 1.40 x 150%
= 1.40 x
150100 = $2.10
1.4 u + 6.3 u = 231
7.7 u = 231
1 u = 231 ÷ 7.7 = 30
Cost of the kiwis
= 1 u x 1.40
= 1 x 30 x 1.40
= $42
(b)
Number of mangoes ordered
= 3 u
= 3 x 30
= 90
Answer(s): (a) $42; (b) 90
