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

How would you determine what fraction strips with rhe same denominator would fit exactly under 1/2 & 1/3. What are they?

vfiekz [6]

Step-by-step explanation:

$\frac{1}{2} = \frac{1 \times 3}{2 \times 3} = \frac{1}{6} \\ \\ \frac{1}{3} = \frac{1 \times 2}{3 \times 2} = \frac{1}{6}$

${ \boxed{{ \bold{{ \pink{e}}{ \blue{x}}{ \purple{p}}{ \green{l}}{ \red{a}}n{ \purple{a}}{ \orange{t}}{ \red{i}}on}}}}$

we equate first under the fraction (denominator)
find the number of products that allow the denominators to be the same
the result that both fractions have the same denominator
