A company finds that the rate at which the quantity of a product that consumers demand changes with respect to price is given by
d1i1m1o1n [39]

Answer:

q =  5000/x  + 6

Step-by-step explanation:

D´= dq/dx  =  - 5000/x²

dq = -( 5000/x²)*dx

Integrating on both sides of the equation we get:

q = -5000*∫ 1/x²) *dx

q = 5000/x + K   in this equation x is the price per unit and q demanded quantity and K integration constant

If when  1006 units are demanded when the rice is 5 then

x = 5     and   q = 1006

1006  =  5000/5 +K

1006 - 1000 = K

K = 6

Then the demand function is:

q =  5000/x  + 6

The gratuity on a restaurant bill was $18. If a 20% tip was left, what was the original amount of the bill?
nevsk [136]

The original amount of the bill is $90.

Given that, the gratuity on a restaurant bill = $18 and tip = 20%.

We need to find the original amount of the bill.

<h3>What is a gratuity?</h3>

A gratuity is a sum of money customarily given by a customer to certain service sector workers such as hospitality for the service they have performed, in addition to the basic price of the service.

The tip is directly proportional to the total cost

=\frac{18}{0.20} =x

= $90

Therefore, the original amount of the bill is $90.
