Question

Gym charges a $50 activation fee and $17 per month for a membership. If you spend $356, for how many months do you have a gym membership?

The correct answer is: x = 18


    • Hint:
    ○ Form the eqaution using given information.
    ○ Solve the equation.
    ○ Take terms with cofficient at one side and without cofficient at another side.
    • Step by step explanation:
    ○ Given:
    Activation fee for gym = $50.
    Membership per month = $17.
    Total money spent = $356.
    ○ Step 1:
    Let you had membership for x months.
    So,
    Total amount paid for 1 month  = activation fee + monthly membership
    Total amount paid for 1 month  =  50 + 17
    Hence,
    Total amount paid for x month  = activation fee + membership for x month
    Total amount paid for x month  =  50 + 17x
    ○ Step 2:
    ○ As total amount paid is $356.
    ∴ 50 + 17x = 356
    rightwards double arrow17x =  356 - 50
    rightwards double arrow17x = 306
    rightwards double arrowx = 306 over 17
    rightwards double arrowx = 18
    • Final Answer:
    Hence, for 18 months you had membership.
