Answer:
See below.
Step-by-step explanation:
So we know that a gym membership costs $25 plus $14 each month.
In other words, the one-time cost is $25 and there will be a cost of $14 each month.
We can write this as:
[tex]f(x)=14x+25[/tex]
Where f(x) equals the total cost given the number of months x.
For 6 months, the total cost will be:
[tex]f(6)=14(6)+25\\f(6)=84+25\\f(6)=\$ 109[/tex]
