Answer:

C. $D_\frac{1}{7} (P)=P'(\frac{1}{4},-\frac{5}{14} )$

Step-by-step explanation:

$\frac{7}{4}*\frac{1}{7}=\frac{7}{28} =\frac{1}{4}$

$-\frac{5}{2} *\frac{1}{7} =-\frac{5}{14}$

Given the cost function C(x) = 0.81x + 60, 420 and the revenue function R(x) = 1.87x, find the break-even point

Viktor [21]

Answer:

x = 57,542.8571

Step-by-step explanation:

C(x) = 0.81x + 60,420

R(x) = 1.87x

At break even point, Cost function and revenue function becomes equal.

-> C(x) = R(x)

-> 0.81x + 60,420 = 1.87x

-> 60420 = 1.87x - 0.82x

-> 60420 = 1.05x

-> x = 60420/1.05

-> x = 57,542.8571

Thus, at break even point x = 57,542.8571

How much did she spend on food during the three months

Dima020 [189]

Answer:

$ $$563.20$ or ≈$ $563.00$

Step-by-step explanation

The question states that Mrs. Hadley spent $126.97 on one month, $237.81 on the next, and $198.42 on the last. To get the total, we can add these values together.

$126.97+237.81+198.42=563.20$

An estimation would be:

$127+238+198=563$

We can use this estimation to determine that the total value is reasonable.
