Quizplus · Accepted Answer

We plug in x = 200 into the given expressions:

$C(200) = 7(200) + 1000 = 2400$

$A(200) = \frac{C(200)}{200} = \frac{2400}{200} = 12$

$R(200) = \$20(200) = 4000$

$P(200) = R(200) - C(200) = 4000 - 2400 = 1600$

Therefore, the answer is B, 1,600.

= A)1,400 B)1,600 C)1,800 D)1,200

=
A)1,400
B)1,600
C)1,800
D)1,200
