Question

The town librarian bought a combination of new-release movies on DVD for $20 and classic movies on DVD for $8. Let x represent the number of new releases, and let y represent the number of classics. If the librarian had a budget of $500 and wanted to purchase as many DVDs as possible, which values of x and y could represent the number of new-release and classic movies bought?

Answer 1

Welcome to QC!

For questions with price you want to have the variable next to its corresponding cost


Say an item is set to x and that same item costs $50, you would write it as \(50x\)

Answer 2

With that said, you want to create a general equation for the cost

It should look something like this

Cost = {Price of new-release} \(\cdot\) x \(+\) {Cost of classics} \(\cdot\) y

Answer 3

I will do that, thank you!!
