A gym membership costs $25 to join and $14 each month. Write and use an algebraic expression to find the cost of the gym members

lina2011 [118]

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:

$f(x)=14x+25$

Where f(x) equals the total cost given the number of months x.

For 6 months, the total cost will be:

$f(6)=14(6)+25\\f(6)=84+25\\f(6)=\$ 109$
