Answer:

$C=20+0.20N$

Step-by-step explanation:

Fixed monthly fee = $20

Amount charged per minute for long distance calls = $0.20

$C$ denotes total cost such that $N$ minutes are used for long distance calls.

Amount charged for $N$ minutes for long distance calls $=0.20N$

Therefore, an equation for the total cost, C, when N minutes are used for long distance calls is $C=20+0.20N$
