Answer:
$65
Step-by-step explanation:
So we already determined that the total cost C to drive m miles is:
[tex]C=0.25m+40[/tex]
And we want to find the total cost of driving 100 miles.
So, substitute 100 for m and solve for C:
[tex]C=0.25(100)+40[/tex]
Multiply:
[tex]C=25+40[/tex]
Add:
[tex]C=\$ 65[/tex]
Therefore, it will cost $65 to drive 100 miles.
