310Number of kiwis = 3 u
Number of mangoes = 10 u - 3 u = 7 u
Price of each kiwi in percent = 100%
Price of each mango in percent = 100% + 25% = 125%
Price of each mango
= 1.20 x 125%
= 1.20 x
125100 = $1.50
3.6 u + 10.5 u = 141
14.1 u = 141
1 u = 141 ÷ 14.1 = 10
Cost of the kiwis
= 3 u x 1.20
= 3 x 10 x 1.20
= $36
(b)
Number of mangoes ordered
= 7 u
= 7 x 10
= 70
Answer(s): (a) $36; (b) 70
