- What is the total effect on the economy of a government tax rebate of $500 to each household in order to stimulate the economy if each household will spend of the rebate in goods and services?A private investment club has $3,000 earmarked for investment in stocks. To arrive at an acceptable overall level of risk, the stocks that management is considering have been classified into three categories: high risk, medium risk, and low risk. Management estimates that high-risk stocks will have a rate of return of 17%/year; medium-risk stocks, 7%/year; and low-risk stocks,6%/year. The members have decided that the investment in low-risk stocks should be a quarter of the sum of the investments in the stocks of the other two categories. Assuming that all the money available for investment is invested, how much should the club invest in each type of stock if the investment goal is to have a return of $413/year on the total investment? (Round your answer to 1 decimal place.)In the original RedBrand problem (Example 5.4), suppose that the company could add up to 100 tons of capacity, in increments of 10 tons, to any single plant. Use SolverTable to determine the yearly savings in cost from having extra capacity at the various plants. Assume that the capacity will cost $28,000 per ton right now. Also, assume that the annual cost savings from having the extra capacity will extend over 10 years, and that the total 10-year savings will be discounted at an annual 10% interest rate. How much extra capacity should the company purchase, and which plant should be expanded? (Hint: Use the PV function to find the present value of the total cost saving over the 10-year period. You can assume that the costs occur at the ends of the respective years.)
