Question

If you rent a car for one day and drive it for 100 miles, the cost is $40.00. If you drive it 150 miles, the cost is $48.00. Use the function to find how much it will cost to rent the car for 1 day if you drive 200 miles?

Answer 1

Typeo*
You've got the coordinates:
\[(x_{1},y _{1})=(100,40)\]
and
\[(x_{2},y _{2})=(150,48)\]
And you know the linear function
\[f(x)=ax+b\]
Find a and b, and you've got your function :)

Answer 2

I think it will cost $56

Answer 3

You're not supposed to give the answer ?

Answer 4

\[a=\dfrac{x_{2}-x_{1}}{y_{2}-y_{1}}\]and
\[b=a\cdot x-y\]
