College Algebra Question

Question

Hugh is trying to decide between two laser printers. Both have similar features and​ warranties, so price is the determining factor.

Printer A costs

​$175

and printing costs are approximately

​$0.07

per page. Printer B costs

​$164

and printing costs are approximately

​$0.11 per page. How many pages need to be printed for the cost of the two printers to be the​ same?

Answer 1

You will need to set up an equation showing the two expressions equivalent and solving for the variable.

Let x-number of pages being printed

0.07x +175 = 0.11x +164

-0.07 -0.07

_____________________

175 = 0.04x + 164

-164 -164

________________

11 = 0.04x

divide each side by 0.04 and x = 275 pages

You can plug in 275 for x on each side to see that they are equal on each side.
