Answer:
a.
b.
c.
Step-by-step explanation:
a) The marginal cost function is given by the derivative of the total cost function, in this way the marginal cost function for this company is:
b) The income function is given by the relation .
The marginal revenue function for the company is given by the derivative of the revenue function, in this way the marginal revenue function is:
(c) The profit function of the company is given by the relation , and the marginal utility function is given by the derivative of the utility function, in this way , the marginal utility function is:
When q = 2000, the marginal utility is:
When q = 7000, the marginal utility is:
Ralph chase invested $85000 at an interest of 10% and $70000 at an interest of 8%
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.
Let a represent the amount invested at interest of 10% and b represent the amount invested at 8%, hence:
a + b = 155000 (1)
Also:
0.1a + 0.08b = 14100 (2)
From both equations:
a = 85000, b = 70000
Ralph chase invested $85000 at an interest of 10% and $70000 at an interest of 8%
