Is that the entire problem?
Is the problem that one wants to know the number of months of gym membership that can be pre-paid, given that the person enrolling has $150.00 to spend as of right now?
This would be: 22 + 16x ≤ 150
Next, to solve for 'x', we need to subtract 22 from both sides, to give us:
16x ≤ 128
To determine the number of months that can be pre-paid, divide out both sides by '16', to get:
x ≤ 8
So, the maximum number of months that can be pre-paid is 8.
