MRS, JOHNSON JUST PURCHASED A TOTAL OF 12 BOOKS AND MAGAZINES FOR HER OFFICE. THE TOTAL BILL WAS $112. SHE SPENT $16 ON MAGAZINES AND THE BOOKS COST $12 EACH. HOW MANY BOOKS DID SHE BUY?

Respuesta :

To do this problem, we can right an equation assuming the number of booked she bought is x:

16 + 12x = 112

First we will isolate the variable by subtracting 16 from both sides:

12x = 96

Then we will divide each side by 12:

x = 8

Since the number of books she bought is x, that must mean that:

Mrs. Johnson bought 8 books.

The number of books that Mrs Johnson bought is 8 books

Let x represent the number of books she bought

First step is to formulate an equation

12x + 16 = 112 dollars

Second step is to transpose

12x=112-16  

12x = 96

Third step is to divide both side by 12

x=96/12  

x = 8

Inconclusion the number of books that Mrs Johnson bought is 8 books
