Solve janet piano teacher charged $12.50 for a 30-minute lesson if janet has a 4 lesson per month how much will she owe her piano teacher a year

You would multiply 12.50 by 4 because thats how much each lesson is and you go 4 times a month. You then multiply this by 12 because there are 12 months in a year. The answer comes out to $600 a year. Hope this helps. XD
