Question

A hair product company sells three types of hair products for $30, $20, and $10 per unit. In one year, the total revenue for the three products was $800,000, which corresponded to the sale of 40,000 units. The company sold half as many units of the $30 product as units of the $20 product. How many units of each
product were sold?

Answer 1

30x+20y+10z = 800000
x+y+z = 40000
x = y/2

x=10,000
y=20,000
z=10,000
