if C(m)= 0.50m+30 represents the cost of renting a car, how many miles were driven if the cost is $130?
m=#miles
so 130= .5m+30
subtract 30 from each side
100$= .5m than divide .5 to isolate m
m= 200
Answer:
200 miles is the answer.
Step-by-step explanation:
Given relation is : C(m)= 0.50m+30
C(M) = Cost for renting a car
0.50m = Cost per mile driven
30 = Initial cost
M = Miles driven
Now putting 130 in place of c(m)
\(130=0.50m+30\)
\(0.50m=130-30\)
\(0.50m=100\)
\(m=\frac{100}{0.50}=200\)
Therefore, if the cost is $130, then 200 miles were driven.
