The DingGnat Doorknob Company intends to sell a new line of square doorknobs. The price-demand function is p ( x ) = 48.5 − 0.09

pickupchik [31]

Answer:

a. 135 doorknobs

b. $R(x) = 48.5x-0.09 x^2$

Step-by-step explanation:

The price-demand function is:

$p(x) = 48.5-0.09 x$

a. At a price of $36.30, the number of doorknobs sold, 'x' is:

$p(x) = 48.5-0.09 x\\36.30 = 48.5-0.09 x\\x= \frac{48.5-36.30}{0.09}\\x=135.55$

Rounding it down to the nearest whole unit, the company can sell 135 doorknobs at $36.30

b. Revenue is the product of the price, p(x), by the demand, x. Therefore, the Revenue function is:

$R(x) = x*p(x)=x(48.5-0.09 x)\\R(x) = 48.5x-0.09 x^2$

MissTica

Answer:

On a fair die, half the numbers are even and half the numbers are odd. So, the probability for a single roll of getting an even number or an odd number is 12. So, the odds are 7:1 against the desired outcome
