Question

The equation y=15x+30 describes the relationship between the number of months since a customer began renting a storage unit and the total amount of money, in dollars, the customer has paid to the storage facility. Which statement describes a solution of the equation based on the number of months of customer has rented the storage unit

Answer 1

It will add 15 dollar for each month.

Answer 2

This function starts at 30 where x=0, and then gains 15 units each time x is increased by 1.

So, we deduce that renting the storage has a fixed price of 30, and then you have to pay 15 each month.
