Question

Write an equation to solve

The library bought books at $15 each and a video rack for $35. These purchases cost $395 altogether. How many books were bought?

Answer 1

24 books

steps:

If we take the amount 395 and subtract 35, we get a total that is unaffected by the video rack, and can be easily answered now

The total is 360, we are now able to divide 360 by 15, getting the total of 24 books
