Question

You return several shirts to a store. The receipt shows that the amount placed back on your credit card is − $30.60. Each shirt is − $6.12. How many shirts did you return?

Answer 1

I did this on a calculator may or may not be correct but I got 18

Answer 2

You would have returned 5 shirts. To find this answer you would have to multiply the unknown variable (x), which represents the number of shirts by the price of each shirt. That would look like this: 6.12(x)=30.60.
You can use many methods to find x but the easiest one for me is the substitution method. This is the method where you substitute numbers to find the approximate one. In this case x would be 5. There was five shirts returned.
