Given the statement:
C(m)= 0.50m+30 represents the cost of renting a car,
Determine how many miles is driven if the cost is $130.
Solution:
In order to determine how many miles is driven, we simply needed to equate the 130 to the solution, and solve for m.
C(m)= 0.50m+30
130 = 0.50m + 30
Transpose 30 to the other side of the equation, hence it must be taken to note that in transposing a number, the sign changes.
0.50m = 130 - 30
0.50m = 100
Divide both sides by 0.50 in order to determine the value of m.
0.50m/0.50 = 100/0.50
m = 200 miles
Final answer:
m = 200 miles
