Marginal Propensity to Consume In
Exercises 59 and 60, (a) use the marginal propensity to consume, dQ/dx, to write Q as a function of x, where x is the income (in dollars) and Q is the income consumed (in dollars). Assume that families who have annual incomes of $25,000 or less consume 100% of their income. (b) Use the result of part (a) and a spreadsheet to complete the table showing the income consumed and the income saved, x - Q, for various incomes. (c) Use a graphing utility to represent graphically the income consumed and saved. See Example 8.
X | 25,000 | 50,000 | 100,000 | 150,000 |

- The participation rate is the number of people in the labor force divided by the civilian population (excludes military). Let L(x) represent the size of thelabor force in year x, and P(x) represent the civilian population in year x. Determine a function that represents the participation rate R as a function of x.arrow_forwardAnalyzing critical points Find the critical points of the following functions.Use the Second Derivative Test to determine (if possible) whether each critical point corresponds to a local maximum, a local minimum,or a saddle point.

- Demand function for pizzas After studying sales for several months,the owner of a pizza chain knows that the number of two-topping pizzas sold in a week(called the demand) decreases as the price increases. Specifically, her data indicate thatat a price of $14 per pizza, an average of 400 pizzas are sold per week, while at a price of$17 per pizza, an average of 250 pizzas are sold per week. Assume that the demand d is alinear function of the price p.a. Find the constants m and b in the demand function d = f(p) = mp + b. Then graph f .b. According to this model, how many pizzas (on average) are sold per week at a price of$20?arrow_forwardTransforming functions.arrow_forwardComposition of function and pigeonhole principlearrow_forward
