40100 =
25Number of starfruits = 2 u
Number of kiwis = 5 u - 2 u = 3 u
Price of each starfruit in percent = 100%
Price of each kiwi in percent = 100% + 40% = 140%
Price of each kiwi
= 2.50 x 140%
= 2.50 x
140100 = $3.50
5 u + 10.5 u = 403
15.5 u = 403
1 u = 403 ÷ 15.5 = 26
Cost of the starfruits
= 2 u x 2.50
= 2 x 26 x 2.50
= $130
(b)
Number of kiwis ordered
= 3 u
= 3 x 26
= 78
Answer(s): (a) $130; (b) 78
