Question

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

Answer 1

15 month

Explanation:

Total amount = registration fee + no. of month × monthly fee

$400 = $100 + no. of month × $20

no. of month × $20 = $400 - $100

no. of month = $300 ÷ $20

= 15 month
