Laura rents a movie for a flat fee of $2.00 plus an additional $0.50 for each night she keeps the movie. If Laura keeps the movie for 3 nights, how much will she pay when she returns it?

Question

pfenn1 · Answer

The total cost = the flat fee plus 0.50 times the number of nights.  Can you write the equation for this?

anonymous · Answer

x=2.00+0.50(3)     something like that?

pfenn1 · Answer

Correct.  The more general form of the equation would be$$x=2.00+0.5n$$ where n=number of nights the movie was kept.

anonymous · Answer

So i plug 3 in for n then solve for x?

pfenn1 · Answer

Yes.  Exactly like the equation you wrote.  I was just pointing out that the equation you wrote was specific for 3 nights and that you could write it in a more general sense.

anonymous · Answer

okay , :) $$x=2.00+0.50(3)$$ that would be the equation

anonymous · Answer

$$x=3.50 $$ is the anwser
