Question 1186327: Use two equations in two variables to solve the problem.
A coffee supply store waits until the orders for its special coffee blend reach 100 pounds before making up a batch. Coffee selling for $7.40 a pound is blended with coffee selling for $3.65 a pound to make a product that sells for $5.15 a pound. How much of each type of coffee should be used to make the blend that will fill the orders?

100 pounds mixture, blend price $5.15 per pound
$7.4 per pound
$3.65 per pound

v, how much of the $7.4 per pound coffee
u, how much of the $3.65 per pound coffee (because directions say, "use two equations in two unknowns".)
100-v, how much the $3.65 per pound coffee
