25Number of pears = 2 u
Number of guavas = 5 u - 2 u = 3 u
Price of each pear in percent = 100%
Price of each guava in percent = 100% + 40% = 140%
Price of each guava
= 1.50 x 140%
= 1.50 x
140100 = $2.10
3 u + 6.3 u = 186
9.3 u = 186
1 u = 186 ÷ 9.3 = 20
Cost of the pears
= 2 u x 1.50
= 2 x 20 x 1.50
= $60
(b)
Number of guavas ordered
= 3 u
= 3 x 20
= 60
Answer(s): (a) $60; (b) 60
