Answer:

  • g = -1110p +4300.9
  • 804 gallons

Step-by-step explanation:

a) Price is the independent variable, so the data we are given can be written as ...

  (price, gallons) = (2.99, 982) and (2.79, 1204)

Using the 2-point form of the equation for a line, we have ...

  g = (g2 -g1)/(p2 -p1)(p -p1) +g1

  g = (1204 -982)/(2.79 -2.99)(p -2.99) +982

  g = -1110(p -2.99) +982 = -1110p +4300.9

  g = -1110p +4300.9

__

b) When p = 3.15, the predicted sales volume is ...

  g = -1110(3.15) +4300.9 = 804.4

Weekly sales are predicted to be 804 gallons at a price of $3.15.
