310Number of peaches = 3 u
Number of guavas = 10 u - 3 u = 7 u
Price of each peach in percent = 100%
Price of each guava in percent = 100% + 50% = 150%
Price of each guava
= 1.40 x 150%
= 1.40 x
150100 = $2.10
4.2 u + 14.7 u = 189
18.9 u = 189
1 u = 189 ÷ 18.9 = 10
Cost of the peaches
= 3 u x 1.40
= 3 x 10 x 1.40
= $42
(b)
Number of guavas ordered
= 7 u
= 7 x 10
= 70
Answer(s): (a) $42; (b) 70
