When a mutual fund company charges a fee of 0.47% on its index funds, its assets in the fund are $45 billion. When it charges a fee of 0.17%, its assets in the fund are $296 billion. (a) Let x denote the fee that the company charges as a percentage of the index fund and let A(x) denote its assets in the fund. Express A(x) as a linear function of x. (b) One company lowers its fees on various index funds from an average of 0.28% to 0.18%. Let R(x) denote the revenue of the company from fees when its index-fund fee is x%. Compare the revenue of the company before and after lowering the fees. [Hint: Revenue is x% of the assets.] (c) Find the fee that maximizes the revenue of the company and determine the maximum revenue. (a) Let x denote the fee that the company charges as a percentage of the index fund and let A(x) denote its assets in the fund. Express A(x) as a linear function of x. A(x) = - 836.667x + 438.234 (Simplify your answer. Use integers or decimals for any numbers in the expression.
