310Number of grapefruits = 3 u
Number of chikoos = 10 u - 3 u = 7 u
Price of each grapefruit in percent = 100%
Price of each chikoo in percent = 100% + 50% = 150%
Price of each chikoo
= 1.80 x 150%
= 1.80 x
150100 = $2.70
5.4 u + 18.9 u = 243
24.3 u = 243
1 u = 243 ÷ 24.3 = 10
Cost of the grapefruits
= 3 u x 1.80
= 3 x 10 x 1.80
= $54
(b)
Number of chikoos ordered
= 7 u
= 7 x 10
= 70
Answer(s): (a) $54; (b) 70
