Question

To join a local square dancing group, Jan has to pay a $100 registration fee pIus $20 per month. How many months can she dance for $400?

Answer 1

If there will be no increase in mothly payment, she can dance there for 15 months

Explanation:

Let me write an equation.

One-time fee (registration) should be out from the total sum:

`$400-$100`

`=$300`

This is the money available for monthly payments.

For how many months?

`($300)/($20) = 15` months

If there will be no increase in monthly payments in the future, Jan can dance for 15 months.
