Question

adam sells medical magasines and books.

the prices are 8 for magazines and 15 for books.

each week he earns 200+10%of magasine price for each sold and 15% for each book sold

last week he sold 42 magasines and 14 books. how much did he earn

Answer 1

Answer:

Let the Price of 1 magzine = x

        Margin on 1 Magzine = (10%)(x) rupees = 0.1 x    

        Margin on 42 Magzines = 42(0.1 x) = 4.2 x    

Also

Let the Price of 1 books = y

        Margin on 1 Book = (15%)(y) rupees = 0.15 y    

        Margin on 14 Books = 14(0.15 x) = 2.1 y    

Basic Pay of Adam = 200

Amount that Adam earned last week = 200 + 4.2 x  + 2.1 y
