14Number of grapefruits = 1 u
Number of peaches = 4 u - 1 u = 3 u
Price of each grapefruit in percent = 100%
Price of each peach in percent = 100% + 50% = 150%
Price of each peach
= 2.40 x 150%
= 2.40 x
150100 = $3.60
2.4 u + 10.8 u = 330
13.2 u = 330
1 u = 330 ÷ 13.2 = 25
Cost of the grapefruits
= 1 u x 2.40
= 1 x 25 x 2.40
= $60
(b)
Number of peaches ordered
= 3 u
= 3 x 25
= 75
Answer(s): (a) $60; (b) 75
