"Kyle buys books. He pays $4.50 for each hardcover book x. He pays $1.75 for each paperback book y. He pays $32 for 12 books!

Write a system about this.

A. xy = 12
4.50x + 1.75y = 32

B. x + y = 12
4.50x + 1.75y = 32

Answer 1

B

Explanation:

Total number of books = 12

Total amount paid =$32

number of x books + number of y books = Total number of books

Therefore, x+y=12

And, Amount paid for book x + amount for book y = Total amount paid

Therefore, 4.50x + 1.75y = 32

Resulting to;

x + y =12

4.50x + 1.75y = 32.

option: B
