Question

Your gym membership costs $10 a month after an initial membership fee of $50. How long have you had your account if you have paid $300? (Hint: Create an equation to model this situation then solve for the unknown.

Answer 1

y(300)=10x+50

Step-by-step explanation: we know that Y has to be 300 because that is our final amount of money that we have paid. we pay 10 bucks a month for the membership alone. the initail fee is 50 bucks so what you start with. we then can start plugging in numbers to solve for x. if you do x=25 you will get 300.

10(25)+50=300

250+50=300

therefore your equation will be Y=10x+50
