A Regular coffee bag is required to contain at least 5 oz. of Brazilian and 5 oz. of Colombian beans. A Specialty bag contains at least 6 oz. of Kenyan but no more than 4 oz. of Brazilian. Due to potential supply shortages from Brazil, the amount of Brazilian beans in a Regular bag must not be more than 70% of the amount of Brazilian beans used in a Regular and a Specialty bag in total. SCC would like to find the right mix of coffee beans for each Regular and Specialty bag to minimize the total cost.

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
