Answer:

It will take him 20 days to read a 300-page book.

Step-by-step explanation:

Given:

Stephen read a 90-page book in 6 days.

If he continues reading at that rate.

Now, to find the time it will take him to read a 300-page book.

So, we solve using unitary method:

If, Stephen read 90 pages in 6 days.

So, Stephen read 1 page in = $\frac{6}{90}$ days.

Thus, Stephen read 300 page in = $\frac{6}{90} \times 300$

$=\frac{1800}{90}$

$=20\ days.$

Therefore, it will take him 20 days to read a 300-page book.

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 Revenue R is 12000

Lets replace R with 12000 and solve for p

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

Apply quadratic formula

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