Given:
Basic cost = $45
Cost of long distance calls = $0.10 per minute
To find:
The total cost if you had 45 long distance minutes.
Solution:
Let the total cost be y for x minutes long distance calls.
Cost of long distance calls for one minute = $0.10
Cost of long distance calls for x minute = $0.10x
Total cost = Basic cost + Cost of long distance calls for x minute
Substitute x=45, to find the total cost if you had 45 long distance minutes.
Therefore, the total cost if you had 45 long distance minutes is $49.5.
