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.

Answer:

Answers are below in bold

Step-by-step explanation:

1) A = 1/2bh          Use this equation to find the area of each triangular base

A = 1/2(8)(6)         Multiply

A = 1/2(48)           Multiply

A = 12cm²           Area of each triangular base

2) A = L x W        Use this equation to find the area of the bottom rectangular face

A = 20 x 8          Multiply

A = 160 cm²       Area of the bottom rectangular face

3) A = L x W        Use this equation to find the area of the back rectangular face

A = 20 x 6          Multiply

A = 120 cm²       Area of the back rectangular face

4) A = L x W        Use this equation to find the area of the sloped rectangular face

A = 20 x 10         Multiply

A = 200 cm²      Area of the sloped rectangular face

5) To find the total surface area of the triangular prism, add together all of the numbers.

A = 12 + 12 + 160 + 120 + 200       Add

A = 504 cm²       Total area of the triangular prism
