Answer:
The total cost is $735.
Step-by-step explanation:
It is given that a cell phone company charges a $15 activation fee, and then $30 per month.
Fixed changes = $15
Variable changed = $30 per month
Let x be the number of month. So the total cost is defined as
[tex]T(x)=15+30x[/tex]
We need to find the total cost for 24 months.
Substitute x=24 in the above equation.
[tex]T(24)=15+30(24)[/tex]
[tex]T(24)=15+720[/tex]
[tex]T(24)=735[/tex]
Therefore, the total cost is $735.
