Question 352947: To rent a van it intially costs $87 down plus $.031 per mile.
Write a fuction that describes the total cost of renting the van. I dentify the independent and dependent variables and tell what each one represents.
How far can you drive the van if you have $275? What is the cost if you drive 1358 miles?

Let C = total cost of renting the van. This is the dependent variable.
Let x = number of miles the van was driven. This is the independent variable.
Then C+=+0.031%2Ax+%2B+87.
If C+=+%24275, then 275+=+0.031%2Ax+%2B87.
275-87+=+0.031%2Ax
188+=+0.031%2Ax
x+=+6064.52miles.
If x+=+1358
C+=+0.031%2A1358+%2B87+=+129.10$.
