Question

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?
A)5,000
B)5,500
C)50,000
D)55,000

Answer 1

P=25r-12500
p=125000 and r=?

125000=25r-12500
+12500       +12500
25r= 137500
r=137500/25
r= 5,500

Therefore the answer is B) 5,500
