X = -20p + 500
20p = 500 - x
p = (500 - x)/20

R = xp = x(500 - x)/20 = (500x - x^2)/20

X = - 20 p + 500
First we have to express p as a function of x:
20 p = - x + 500  / : 20
p = - x/20 + 25
The revenue:
R = x p
R = x ( - x/20 + 25 ) = - x²/20 + 25 x

Marvin used the money he received from
Kay [80]

Answer:

<em>Correct choice: C. $320</em>

Step-by-step explanation:

<u>Simple Interest</u>

Definition: Interest calculated on the original principal only of a loan or on the balance of an account.

Unlike compound interest where the interest earned in the compounding periods is added to the new principal, simple interest only considers the principal to calculate the interest.

The interest earned is calculated as follows:

I=P.r.t

Where:

I = Interest

P = initial principal balance

r = interest rate

t = time

Marving is saving money in a savings account with a simple interest rate of r=7.5%=0.075. It's known that after t=12 years, the account had earned $288 interest. Substituting in the formula:

288 = P*0.075*12

Calculating:

288 = 0.9P

Dividing by 0.9:

P = $320

Correct choice: C. $320

Find the values of the variables in each figure.
Diano4ka-milaya [45]

Answer:

x = 40

Step-by-step explanation:

2x = 4x - 40 (recall properties of a parallelogram)

Solve for x

2x - 4x = 4x - 40 - 4x (subtraction property of equality)

-2x = -40

-2x/-2 = -40/-2 (division property of equality)

x = 20
