Sharon has a total of $230,000 to invest in three types of mutual funds: growth, balanced, and income funds. Growth funds have a rate of return of 12%/year, balanced funds have a rate of return of 10%/year, and income funds have a return of 6%/year. The growth, balanced, and income mutual funds are assigned risk factors of 0.1, 0.06, and 0.02, respectively. Sharon has decided that at least 50% of her total portfolio is to be in income funds and at least 25% of it in balanced funds. She has also decided that the average risk factor for her investment should not exceed 0.05. How much should Sharon invest in each type of fund in order to realize a maximum return on her investment? Hint: The constraint for the average risk factor for the investment is given by 0.1x + 0.06y + 0.02z ≤ 0.05(x + y + z).growth funds $: balanced funds $: income funds $: What is the maximum return?

Your classmate wants you to check her work. She is working on a math question that asks her to determine the slope of a line given on a graph. You can see that the graph is a line, and that the line is increasing. Your classmate says that it’s a positive slope but you are not sure of the explanation. She tells you that she went down 5 units and to the left 3 units to the next point on the line to determine the slope. Determine if your classmate is correct and explain why or why not.
