Rod and Reel, Inc. manufactures and sells fishing rods. The company uses the equation P = 25r – 12,500 to estimate its profit P on the sale of r fishing rods. How many fishing rods were sold if the company made a profit of $125,000?

Answer :

VenusRetrograde
Answer: r=5,500

P=$125,000

P=25r-12,500
substitute P for 125,000
125,000=25r-12,500
add 12,500 to both sides
137,500=25r
divide both sides by 25
5500=r

The company sold 5,500 fishing rods
