Question

Your gym membership costs $30 to join and $25 per month. Which equation gives the total costs y, for a membership that lasts x months?

Answer 1

y=$25x+30

Explanation:

This is the correct answer. The reason is that the equation is y=mx + b. b is like y-intercept, and that answer would be $30. $25x is correct because the question says per month, and when you see that it means ¨x¨.
