A submarine descends to -100 feet in 2 minutes and -250 feet in five minutes. Write and solve an equation to find the depth of the submarine in 8 minutes.

-400

Step-by-step explanation:

So, to find what the depth would be in 8 minutes, you have to find the depth for ONE minute. So, you divide -100 by 2 and you get -50 in a minute. Next thing you do is you multiply -50 by 8. You get -400. And there's your answer!
