An economist is interested in how the price of a certain item affects its monthly sales. At a price of $p, a quantity, q, of the item is sold each month. Suppose that we write q=D(p). Using complete and descriptive sentences, explain the meaning of each of the following statements: a) D(500) = 2,000. b) D'(500) =-25.

For a subsistence agricultural household, which of the following happen when the price of the staple they are producing increases? [SelectMultiple] Group of answer choices Due to profit effect, their utility as producers increases. The impact on overall welfare of the household is ambiguous since it depends on the relative forces of profit effect and price effect. Their is no effect since subsistence households never sell or buy their staple production. Due to price effect, their utility as consumers decreases.

Using the midpoint method, if the price of an airline ticket from San Diego to Kansas City changes from $274 to $670, what is the percentage change in price? The price of an airline ticket from San Diego to Kansas City changes by percent. [Enter your answer in percent, rounded to two decimals.)

Jerry's utility function is U(x,y) = ( 5x + y ) 18. Find Jerry's MRS (for good X in terms of good Y) and then find the value of the derivative dMRS/dx at the point were x=39 and y=69 and enter it below. Remember to enter the number in decimal form. If the number is negative, then use the negative sign (e.g., -3.29839).

MICROECONOMICS  Questions 3  ( ALL OF IT IS ONE QUESTION!!!) For article 3 write the number of the graph that best describes what happened. Fill in only the appropriate boxes in the chart for article 3 and be sure and indicate if it is an increase or a decrease.  For the graph use an arrow to indicate an increase or a decrease. Make sure you fill in the graph PLEASE Leave it blank if there is no change   Masks (Now). The easing Covid-19 pandemic is expected to reduce demand for medical masks this year, joining a group of companies that have forecast a decline in business from Covid-19 prevention. Masks became a billion-dollar business for the St. Paul, Minn., manufacturer starting in 2020, when the virus’s rapid spread sent consumers and healthcare workers looking to secure facial coverings to try to avoid infection. Now, as the latest U.S. surge caused by the Omicron variant fades, 3M said they are seeing slowing mask sales. WHICH GRAPH BEST FITS THE ARTICLE.   Graph # Graph…

Utility is a type of function that occurs in economics. When a consumer receives x units of a certain product, a certain amount of pleasure, or utility U, is derived. The graph represents a typical utility function. a) Find the average rate of change of U as x changes from 0 to 1; from 1 to 2; from 2 to 3; from 3 to 4. b) Why do the average rates of change decrease as x increases? a) The average rate of change of U as x changes from 0 to 1 is. (Type an integer or a decimal.) C Utility (pleasure units) AU 200- 150- 100- 50- 0 (1,67) (2,106) I (3,134) (4,156) 2 Number of units of product 4 X

Explain which of the following is the independent variable and which is the dependent variable for each of the following examples. Once you determine the price of a flash drive at the college bookstore, you will decide how many flash drives to buy. You will decide how many credit hours to register for this semester once the university tells you how many work-study hours you will be assigned. You anticipate earning a higher grade on your economics exam because you studied more hours in the weeks preceding the exam.

13. Suppose that AS = 3SAT + 2SAX and that today's price is S(0) = 50. Find (i.e., derive) the PDF for the price of S(1), the price one year from now.

Tim is buying pizza and salad for a company lunch. Suppose that a slice of pizza costs $4.00, and a bowl of salad costs $5.00. Let ♬ be the amount in dollars that Tim spends on pizza and salad. If Tim buys P slices of pizza and S bowls of salad, then the total amount of money he spends (B) can be represented by the equation Now rearrange the equation you wrote above so that S is written in terms of E and P. The quantity of salad he buys can be represented by the equation Suppose Tim has $40.00 to spend on pizza and salad; that is, E = $40.00. Complete the following table with the values of P or S that make the equation true. Hint: To complete the first row, determine the number of salad bowls Tim can purchase with $40.00, when the number of pizza slices he purchases is 0. Budget Pizza (Dollars) (Slices) 40.00 0 40.00 5 40.00 Use the black line (plus symbols) to plot the line illustrating the combinations of pizza and salad that Tim can purchase with a budget of $40.00.
