#### Transcripts - Linear Equation Pool Filling and Apple Pickers Questions

• 1. 1) A pool already has 400 gallons in it. It is being filled at a rate of 50 gallons per minute. Write an expression that gives the gallons of water in the pool as a function of time. 2) An Olympic size pool holds a half a million gallons. It is being emptied at a rate of 60 gallons per minute. Write an expression that gives the gallons of water in the pool as a function of time. 3a) A fast apple picker gets \$20/hour. Write an expression of her pay as a function of time. Graph the equation. Label the graph. 3b) A new apple picker earns \$10/hour. He receives \$50 extra the first day for being a new hire. Write an expression of his pay as a function of time. Graph the equation on the same graph as #3a. 3c) Analyze the graph in words. Determine when the apple pickers earned the same amount. Describe before they earn the same and after they make the same.
