Aura currently pays \$800 each month to rent her apartment.  Due to inflation, however, her rent is increasing by \$50 each year.  Meanwhile, her monthly take-home pay is \$1500 and she predicts that her monthly pay will only increase by \$15 each year.  Assuming that her rent and take-home pay will continue to grow linearly, will her rent ever equal her take-home pay?  If so, when?  And how much will rent be that year?

Let the number of years when her rent and her pay will equalize=N, so we have:

800 + 50N =1,500 + 15*12N

180N - 50N = 800 - 1,500

130N = -700 From this you can deduce that her rent will NEVER catch up with her pay.
