Agrocer mixes peanuts that cost $2.49 per pound and walnuts that cost $3.89 per pound to make 100 pounds of a mixture that costs $3.19 per pound. how much of each kind of nut is put into the mixture

Let a be the amount of peanuts; and

Let b the amount of walnuts

Equation 1 would be: A + B = 100

249a + 389b = 319 (100)

Equation 2 would be: 249a + 389b = 31900

From equation 1:

a = 100 – b

249 (100 – b) + 389b = 31900

24900 – 249b + 389b = 31900

140b = 7000

b = 50 lbs

then from equation 1:

A + 50 = 100

A = 50 pounds

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.

step-by-step explanation:

x+2> 6

subtract 2 from each side

x+2-2 > 6-2

x > 4

there is an open circle at 4 since is it is greater than and the line goes to the right
