Math Models Unit 4 Lesson 8

Use the values and the equation of line of best fit to predict the revenue when the price was $10 per unit.

a = -0.5 b = 24 c = -155 revenue = $35 (thousands)

Use the values and the equation of line of best fit to predict the revenue when the price was $15 per unit.

a = -5.05 b = 115 c = -158.10 revenue = $430.65

Use the values and the equation of line of best fit to predict the height after 9 seconds.

a = -5.06 b = 37.75 c = 111.95 height = 41.84

5. Find the values of a, b, and c. Use the values and the equation of line of best fit to predict the cost of producing 15,000 units.

a = 1.4 b = -22 c = 92 cost of producing = $77 (thousands)

Use the values and the equation of line of best fit to predict the cost to produce only 1,000 units.

a = 4 b = -48.5 c = 167.5 cost to produce = $123 (thousands)
