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 on the fishing rods. How many fishing rods were sold if the company made a profit of 125,000?
Please help. Thank you
I got 5500 as the answer
I think you are suppose to add the 12,500 not subtract it.
Ahh, thank you for catching my stupid mistake! I goofed!
125,000 = 25r - 12,500
137,500 = 25r
5,500 = r
You're welcome and thank you
Yes your right you add it because u have -12500 that has to become zero because whatever u do on one side of the eqn you have to do on the other I did the math myself r=5500!!!!
I just went over my arithmetic and still get 4,500. How did you get 5500?
Thanks
4500
To find the number of fishing rods sold, we need to solve the equation P = 25r - 12,500 for the value of r, which represents the number of fishing rods sold.
Given that the company made a profit of 125,000, we can substitute P = 125,000 into the equation:
125,000 = 25r - 12,500
To isolate the variable r, we need to move -12,500 to the other side of the equation by adding it to both sides:
125,000 + 12,500 = 25r - 12,500 + 12,500
137,500 = 25r
Finally, to solve for r, we divide both sides of the equation by 25:
137,500/25 = 25r/25
5,500 = r
Therefore, the company sold 5,500 fishing rods in order to make a profit of 125,000.
P= 25r - 12,500
125,000 = 25r - 12,500
112,500 = 25r
112,500/25 = r
4,500 = r
