310Number of guavas = 3 u
Number of mangoes = 10 u - 3 u = 7 u
Price of each guava in percent = 100%
Price of each mango in percent = 100% + 50% = 150%
Price of each mango
= 1.60 x 150%
= 1.60 x
150100 = $2.40
4.8 u + 16.8 u = 324
21.6 u = 324
1 u = 324 ÷ 21.6 = 15
Cost of the guavas
= 3 u x 1.60
= 3 x 15 x 1.60
= $72
(b)
Number of mangoes ordered
= 7 u
= 7 x 15
= 105
Answer(s): (a) $72; (b) 105
