Question 926816
y equals -100 + .3x
x = kilograms of ingredients.
y = liters of drug.
how much ingredient would be used to produce 100 liters of the drug?
replace y with 100 and solve for x.
y = -100 + .3x becomes:
100 = -100 + .3x
add 100 to both sides of the equation to get:
200 = .3x
divide both sides of the equation by .3 to get:
666.6666666...7 kilograms of ingredients.
this can be translated to 666 and 2/3 kilograms of ingredients.
