25Number of mangosteens = 2 u
Number of kiwis = 5 u - 2 u = 3 u
Price of each mangosteen in percent = 100%
Price of each kiwi in percent = 100% + 50% = 150%
Price of each kiwi
= 2.20 x 150%
= 2.20 x
150100 = $3.30
4.4 u + 9.9 u = 429
14.3 u = 429
1 u = 429 ÷ 14.3 = 30
Cost of the mangosteens
= 2 u x 2.20
= 2 x 30 x 2.20
= $132
(b)
Number of kiwis ordered
= 3 u
= 3 x 30
= 90
Answer(s): (a) $132; (b) 90
