Question

A store owner wants to develop a new snack mix by mixing chocolate and trail mix. How many pounds of chocolate costing $17.70 per pound should be mixed with 15 pounds of trail mix costing $3.20 per pound to create a mixture worth $10.45 per pound.

 

The owner needs to mix_____? pounds of chocolate (round to the nearest whole pound)

Answer 1

If we add p pounds of the $17.70 to 15 pounds

of the $3.20 we end up with 15+p pounds of mixture.

 

17.7p + 3.2(15) = 10.45(15+p)

 

Solve the equation for p.
