Players on the school soccer team are selling candles to raise money for an upcoming trip. each player has 24 candies to sell. if a player sells for candies, a profit of $30 is made. if he sells 12 candies, a profit of $70 is made. the profit and the number of candies sold form a linear relation. what is the slope and what does it mean in this problem?

Slope, M  = 5  and this means that profit is five (5) times  every  unit change in the quantity of candies.

Step-by-step explanation:

Let the equation below represent the Profit and number of candies relationship:

π (x) = Mx +c (1)

Where  π = Profit

            x  = Number of candies sold

            M = Slope of the linear relationship/ equation

             C = The profit intercept of the linear equation or relationship

From the question two different coordinates of profit and the number of candies where given: (π₁ ,x₁)  and (π₂ ,x₂)

First coordinate (π₁ ,x₁)  = ($30 , 4)

Second coordinate (π₂ ,x₂)  = ($70, 12)

These can be substituted into equation (1) and (2) to calculate the for M & C

Substituting the first coordinate into (1) we have :

30 =  4M +C(2)

Substituting the second coordinate into (1) we have :

70 = 12M +C(3)

Solving equation  (2) and (3) simultaneously using elimination method, we have:

30 =  4M +C

70 = 12M +C

-40 = -8M

M = 5

Substituting the value of M into equation (3) we have:

70 = 12(5) +C

70 = 60 +C

C =10

Substituting the value of M and  C into equation (1), we have the Linear relationship for profit and the number of candies sold as

π (x) = 5x + 10 (4)

Slope  = 5  and this means that profit changes five (5) times for every  unit change in the quantity of candies.

use this formula:

p(a\b) = p(a and b)/p(b).
