Suzy borrows $370 from her parents.

Question

She has committed to pay them back at a rate of $30 a month. Write an equation that represents this arrangement that she has made with her parents.

Answer 1

370 = 30 * m

where m is the number of month that she has to pay. m = 370/30, which is greater than 12, so she has to pay 12 months and 10 dollars on top of that.
