25Number of guavas = 2 u
Number of pears = 5 u - 2 u = 3 u
Price of each guava in percent = 100%
Price of each pear in percent = 100% + 60% = 160%
Price of each pear
= 1.50 x 160%
= 1.50 x
160100 = $2.40
3 u + 7.2 u = 51
10.2 u = 51
1 u = 51 ÷ 10.2 = 5
Cost of the guavas
= 2 u x 1.50
= 2 x 5 x 1.50
= $15
(b)
Number of pears ordered
= 3 u
= 3 x 5
= 15
Answer(s): (a) $15; (b) 15
