The owner of a grocery store finds she can sell about 982 gallons of milk in a week if she prices it at $2.99 per gallon. If she

drops the per-gallon price to $2.79, her weekly sales increase to about 1,204 gallons. Assuming a constant rate of change.
a. Find a model that gives weekly milk sales, in gallons, as a function of the per-gallon dollar price.
b. Predict this store owner's weekly milk sales if she sets the per-gallon price to $3.15. Only enter the number, in gallons, rounded to nearest integer.

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.

What is the equation for the line in slope-intercept form?
masha68 [24]

Answer:

y=mx+b is slope-intercept form

where m is the slope and b is the y intercept.

Since the line crosses the y axis at 0,0 the intercept is +0 or just nothing.

now all we need to do is find the slope

to do that just go from the y intercept (the first point) y units up and x units over untill u cross at the next point. for examples from (0, 0) to (1, 8)-the next point- i need to go up 8 units up and 1 unit over. this is described as rise over run and that is your slope 8/1 rise/run. rise is how many units i go up (or down) from the y intercept until the next point that lies on the line and run is how far i need to go over from how many units i just went up. If u continue to go 8 up and 1 over from each point u will see that u get a point lying of the line. This is why 8/1 is your slope

8/1 is the slope and 0,0 is your y intercept so we put nothing

the equation is y=8x
