Comparing Equations with One and Two Variables

Question 1: Patrick has put in 20 hours on a school report so far and plans to work 3 more hours a day until the report is done. Write an equation to model how many total hours (t) Patrick puts into the report based on the number of days (d) he works.

Question 2: Patrick has put in 20 hours on a school report so far and plans to work 3 more hours a day until the report is done. The equation t=20+3d models the total amount of hours Patrick works after d-days. If Patrick wants to spend no more than 35 total hours on the project, how many days can he work at most?

Question 3: Patrick has put in 20 hours on a school report so far and plans to work 3 more hours a day until the report is done. The equation t=20+3d models the total amount of hours Patrick works after d-days. Patrick plans on working 10 more days. How many total hours can he expect to put into the project?

Question 4: A storm has brought 2 inches of snow so far and is expected to bring .5 inches every hour for the duration of the storm. Model this situation using h to represent the number of hours it continues to snow and t to model the total snowfall.

Question 5: A storm has brought 2 inches of snow so far and is expected to bring .5 inches every hour for the duration of the storm. The equation t=.5h+2 models this situation. Is the point (5, 4.5) a solution to the equation? If so, interpret the solution.
