Susan rented a truck for one day. There was a base fee of $12.25, and there was an additional charge of 25 cents for each miles driven.The total cost, C ( in dollars), for driving x miles is giving by the following
C=0.25x+12.25
What is the total rental cost if Susan drove 30 miles?
To find the total rental cost if Susan drove 30 miles, we need to substitute 30 for x in the equation C=0.25x+12.25.
C = 0.25(30) + 12.25
C = 7.5 + 12.25
C = 19.75
Therefore, the total rental cost if Susan drove 30 miles is $19.75.
To calculate the total rental cost, C, if Susan drove 30 miles, we can use the given equation:
C = 0.25x + 12.25
Substitute x with 30 to find the total cost:
C = 0.25 * 30 + 12.25
Multiply 0.25 by 30:
C = 7.5 + 12.25
Add 7.5 and 12.25:
C = 19.75
Therefore, the total rental cost if Susan drove 30 miles is $19.75.
To find the total rental cost if Susan drove 30 miles, we can use the equation C = 0.25x + 12.25, where C represents the total cost and x represents the number of miles driven.
Substituting x = 30 into the equation, we have:
C = 0.25 * 30 + 12.25
Now we can calculate the total rental cost:
C = 7.50 + 12.25
C = 19.75
So, the total rental cost for Susan driving 30 miles would be $19.75.
