Question 1174541: Dark chocolate costs $40 dollars per pound. Mustard costs $5 per pound. Ellie wants to create a 10 pound mixture of the two items that costs $26 dollars per pound. How much dark chocolate and mustard must she buy? Answer by ikleyn(52790) (Show Source):
Your "total cost" equation is
40*C + 5*(10-C) = 26*10
where "C" is the mass of the dark chocolate, in pounds.
From the equation
C = = 6.
ANSWER. 6 pounds of the dark chocolate and 10-6 = 4 pounds of mustard.
