310Number of starfruits = 3 u
Number of kiwis = 10 u - 3 u = 7 u
Price of each starfruit in percent = 100%
Price of each kiwi in percent = 100% + 50% = 150%
Price of each kiwi
= 1.60 x 150%
= 1.60 x
150100 = $2.40
4.8 u + 16.8 u = 432
21.6 u = 432
1 u = 432 ÷ 21.6 = 20
Cost of the starfruits
= 3 u x 1.60
= 3 x 20 x 1.60
= $96
(b)
Number of kiwis ordered
= 7 u
= 7 x 20
= 140
Answer(s): (a) $96; (b) 140
