A manufacturer of breakfast cereals has the opportunity to purchase barley at $3.00 a bushel for 10,000 bushels, if it also buys 5,000 bushels of wheat at $16.00 per bushel. However, the manufacturer does not use any barley in its products, and currently needs 20,000 bushels of wheat. If the current market price of barley is $3.80 per bushel and that of wheat is $15.80 per bushel, should this opportunity be taken, and why?

step-by-step explanation:

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

question 1: step-by-step explanation:

1/4 of 84 = 84÷4= 21

both triangles are similar because 2 is just smaller than the big one 1 is similar because they are facing different way's but are similar to each other
