Question

An advertiser goes to a printer and is charged $46 for 80 copies of one flyer and $60 for 220 copies of another flyer. The printer charges a fixed setup cost plus a charge for every copy of single-page flyers. Find a function that describes the cost of a printing job, if x is the number of copies made

Answer 1

Evan, this type of problem just requires careful thought to turn the English statements into math equations.

Let the fixed charge per print job be F dollars.

Let the per page charge for the two flyers be x and y, respectively.

Then, F + 80x = 46

And F + 260y = 60

We can't solve these equations, since we have 3 variables (X, y, and F) but only 2 equations.
