Question

Write the equation for this situation: the cost, c, in dollars of a car rental is equal to 10 dollars plus 1/2 the miles driven, m

Answer 1

c=10+m/2

Answer 2

The cost C is equal to 10 dollars + half of m
Mathematically,
c=10+m/2
Taking 2 to the left hand side we have
2C=10+M
Take different values of C and M. Assume C to be X and M to be Y. You will get different values of c for different values of m. Plot these co-ordinate points and join them to make a graph.
If the number of miles driven is 12, the cost would be:
2C=10+12
2C=22
C=22/2
C=$11
