920Number of starfruits = 9 u
Number of lemons = 20 u - 9 u = 11 u
Price of each starfruit in percent = 100%
Price of each lemon in percent = 100% + 40% = 140%
Price of each lemon
= 1.50 x 140%
= 1.50 x
140100 = $2.10
13.5 u + 23.1 u = 549
36.6 u = 549
1 u = 549 ÷ 36.6 = 15
Cost of the starfruits
= 9 u x 1.50
= 9 x 15 x 1.50
= $202.5
(b)
Number of lemons ordered
= 11 u
= 11 x 15
= 165
Answer(s): (a) $202.5; (b) 165
