Dan is filling up his water bottle at the drinking fountain. The water flows from the fountain at a rate of 6 ounces per second. His bottle had 10 oz. of water in it when he started to fill it. This scenario can be modeled with the equation W = 6t + 10 where W is the amount of water in the bottle (in oz.) and t is the time spent filling the bottle (in seconds).

How many ounces of water will Dan have in his bottle after filling it for 8 seconds?

Arty is draining his pool. He created a line of fit for the data he gathered and graphed it.

The equation of the line of fit is W = -150h + 1200, which represents how much water was left in the pool in relation to time passed.

Use this graph and equation to answer questions 3 - 5.
