The monthly revenue of a certain company is given by R 820p-7p, where p is the price in dollars of the product the company manuf
lora16 [44]

The revenue will be 12,000 when the price of the product  is $100

Given :

The monthly revenue of a certain company

R=820p-7p^2

We need to find out p when <u>Revenue R is 12000</u>

Lets replace R with 12000 and solve for p

12000=820p-7p^2\\820p-7p^2=12000\\-7p^2+820p-12000=0

Apply <em>quadratic formula </em>

p=\frac{-820\pm \sqrt{820^2-4\left(-7\right)\left(-12000\right)}}{2\left(-7\right)}\\p=\frac{-820\pm \:580}{2\left(-7\right)}\\p=\frac{-820+580}{2\left(-7\right)},\:p=\frac{-820-580}{2\left(-7\right)}\\p=\frac{120}{7},\:p=100

Given that price must be greater than 50

So the revenue will be 12000 when the price of the product  is $100
