Answer 2

Answer:.

75(b - 4) = 450

Explanation:

Given that :

Total amount to spend on books = 450

Total number of books = b

Cost per book = 75

Number of free books = 4

Hence, the number of books sabah will have to pay for will be :

Total Number of books - number of free books

b - 4

Cost of books purchased will be ;

Cost per book * number of books ;

75 * (b - 4)

Total cost = 450

Hence, we have ;

75(b - 4) = 450
