In this problem, we have been given data for two models of a certain car, and we need to find the cost function for each car as a function of miles -driven x.
00:10
So first of all, consider the hybrid car.
00:15
Now, what is the cost function? now, note that the base price is $2 ,290, and we have a cost of $0 .08 per mile.
00:27
So for x miles, we'll have 0 .08 times x.
00:30
And then we just add these two, and this is a required cost function.
00:35
Similarly for the standard one, the base price is given to be 1970, and there is a cost of 11 cents per miles.
00:45
So the cost function is 190 plus 0 .11x.
00:49
And next, we have been asked to determine the break -even miles.
00:53
So the break -even point will have that when these two costs are equal...
