STATION 6 define the variables: write the equation: define the variables: write the equation: Sam was in-charge of a food stand at a baseball game. He sold hamburgers for $3.50 each and soft drinks for $2.50 each. At the end of the day, he sold $525 worth of food and drinks. define the variables: write the equation: Five-Below sells 3-ft charger cords for $3.25 and 6-ft charger cords for $5. Today the store sold $422.50 worth of these cords. Netflix charges a rental fee of $6.50 per movie, plus a $16 monthly membership fee. x = y = x = y = x = y =

  14. Name: Date: Define the variables and write the equation for each. STATION 6 continued define the variables: write the equation: define the variables: write the equation: A plumber charges $85 per hour for labor plus an additional amount for an emergency call. Last week the plumber had a 4-hour emergency call and charged the customer a total of $460. define the variables: write the equation: Sabrina spends an average of $22.50 on each Door Dash delivery in addition to the monthly subscription cost of $10. The Patel family spent $360 eating out last month. They ordered Chic-Fil-A four times and Chipotle 3 times. x = y = x = y = x = y =

  16. Determine the average rate of change for each. STATION 7 Name: Date: The graph above shows the average balance in Mr. Gold's checking account over a 12 month period. Determine the average rate of change from month 2 to month 4. The graph above shows the typical data usage of a cell phone in gigabytes over a month. Determine the average rate of change in the data from day 10 to day 30.

  17. Determine the average rate of change for each. STATION 7 Name: Date: The graph above shows the average balance in Mr. Gold's checking account over a 12 month period. Determine the average rate of change from month 2 to month 4. 1305 - 1806.25 = -501.25 = $ -250.63 per month 4 - 2 2 The graph above shows the typical data usage of a cell phone in gigabytes over a month. Determine the average rate of change in the data from day 10 to day 30. 0.8 - 1.8 = -1 = 0.05 gigabytes used per day 10 - 30 - 20

  18. Determine the average rate of change for each. STATION 7 continued Name: Date: Use the graph to determine the average rate of change from x = 1 to x = 3. Use the table below to determine the average rate of change from x = 5 to x = 13. The pool at the YMCA needs to be emptied for maintenance work. The table on the left shows how fast water is pumped out of the pool at the YMCA at certain times. Find the average rate of change from time t = 1 to t = 8. Include units in your answer.

  19. Determine the average rate of change for each. STATION 7 continued Name: Date: Use the graph to determine the average rate of change from x = 1 to x = 3. -4 - 2 = -6 = - 3 3 - 1 2 Use the table below to determine the average rate of change from x = 5 to x = 13. 38 - 12 = 26 = 13 13 - 5 8 4 The pool at the YMCA needs to be emptied for maintenance work.

Identify the slope & y-intercept. slope: y-intercept: Identify the slope & y-intercept. slope: y-intercept: -20/3 30 (0,90) (0,40) Time (Hours) y = 30x + 90 y = -20/3x + 40 Write the equation in slope-intercept form: Write the equation in slope-intercept form: What does the slope mean in the context of the problem? What does the y-intercept mean in the context of the problem? What does the slope mean in the context of the problem? What does the y-intercept mean in the context of the problem? The air in Drew’s tank decreases 20 cubic feet every 3 minutes OR the air decreases about 6.67 cubic feet per minute. Golf costs $30 per game. The initial cost to join the golf course is $90. Drew’s tank starts with 40 cubic feet of air.
