Question

David went shopping at Staples for school supplies. He bought binders, pencils, and a book bag that cost $72. For binders, he spent $17 less than he did on pencils. In total, he spent $119. How much did he spend on binders?

Answer 1

David spent 30$ on binders.

Explanation:

We know that David spent 72$ on his book bag. We know that in total David spent 119$ in total. We can for sure do 119 - 72 = x in order to cancel out the book bad since we already know the price. In this case, X = 47, so David spent 47$ on pencils and binders. We also know that David spent 17$ less on binders than he did on pencils, so we can use the equation 47 - 17 = binders.

47-17 = 30. David spent 30$ on binders.
