14Number of starfruits = 1 u
Number of pomegranates = 4 u - 1 u = 3 u
Price of each starfruit in percent = 100%
Price of each pomegranate in percent = 100% + 50% = 150%
Price of each pomegranate
= 1.60 x 150%
= 1.60 x
150100 = $2.40
1.6 u + 7.2 u = 220
8.8 u = 220
1 u = 220 ÷ 8.8 = 25
Cost of the starfruits
= 1 u x 1.60
= 1 x 25 x 1.60
= $40
(b)
Number of pomegranates ordered
= 3 u
= 3 x 25
= 75
Answer(s): (a) $40; (b) 75
