Presentation transcript:

Find a linear function to represent each scenario. 1. A square table has one seat on each side. Square tables are pushed together to make banquet tables. Draw banquet table #4 in the pattern below. Then complete the table and write a function to show how the number of seats, S, varies with the number of tables that are pushed together, n.

2. These bridges are constructed using rods to make equilateral triangles. The length of a bridge is the number of rods used to construct the bottom span. Draw bridge #4 in the pattern below. Then complete the table and write a function to show how the number of rods used, R, varies with the length of the bridge, n.

3. Prime Products will pay you a weekly salary of $100 plus 10% of sales. Digit Displays will pay you weekly salary of $300 plus 5% of sales. Show how your total weekly earnings at each store is 4000 a function of your sales. Equations:

4. A Turbo averages 10 miles per gallon, and the gas tank holds 30 gallons. A Tork averages 25 miles per gallon, and its gas tank holds 16 gallons. If both cars start with full tanks, show how the amount of gas left in the tank is a function of the number of miles driven. Equations:

Finding Linear Functions Homework An oak tree is 30 ft. from an elm tree. A snail started crawling from the oak to the elm at a rate of 4ft/h. A turtle started crawling from the elm to the oak at a rate of 5 ft/h. Show how the distance of each animal from the oak tree is a function of time since they started crawling.
