Atown has accumulated
5
inches of snow, and the snow depth is increasing by
5
inches every hour. a nearby town has accumulated
9
inches, and the depth is increasing by
3
inches every hour. in about how many hours will the snowfall of the towns be equal?

In 2 hours the snowfall will be equal in both of the towns.
You start off with 5 in T1 and 9 in T2 if T1 is growing by 5in every hour and T2 is growing by 3in every hour.

You take 5in then add it to anther 5in that makes 10in

You take 9in then add it to 3in and you get 12in

Do those steps until you have the same number for each town

100$ would be the correct answer
