310Number of peaches = 3 u
Number of mangoes = 10 u - 3 u = 7 u
Price of each peach in percent = 100%
Price of each mango in percent = 100% + 50% = 150%
Price of each mango
= 2.80 x 150%
= 2.80 x
150100 = $4.20
8.4 u + 29.4 u = 189
37.8 u = 189
1 u = 189 ÷ 37.8 = 5
Cost of the peaches
= 3 u x 2.80
= 3 x 5 x 2.80
= $42
(b)
Number of mangoes ordered
= 7 u
= 7 x 5
= 35
Answer(s): (a) $42; (b) 35
