Answer:
$22.6 markup
Step-by-step explanation:
Just find 20 percent of 113 and you’ll get 22.6
if you want price including the markup (final price) its $139.6
The breakeven point is that in which the total cost is just equal to the total revenue. In other words, the profit becomes zero. The revenue and cost will be given below.
(1) Total revenue = ($200)x
(2) Total cost = ($120)(x) + 1200
Equating,
200x = 120x + 1200
Solving for x gives us an answer of 3.33
Hence, the answer is 3.33.
Part A: After 9 days the radius of algae was approximately 12.81 mm. The reasonable domain to point is (0,9).
Part B: The 9 on the y-intercept represents the amount of algae the experiment started with.
Part C: (12.81-10.12)/7=0.38
Answer:
<em>The x-coordinate is changing at 10 cm/s</em>
Step-by-step explanation:
<u>Rate of Change</u>
Suppose two variables x and y are related by a given function y=f(x). If they both change with respect to a third variable (time, for instance), the rate of change of them is computed as the derivative using the chain rule:

We have

Or, equivalently

We need to know the rate of change of x respect to t. We'll use implicit differentiation:

Solving for dx/dt

Plugging in the values x=1, y=3, dy/dt=5

The x-coordinate is changing at 10 cm/s
