\( 3 i l l \) nterest. In his passbook account, he earns \( 5 \% \) simple interest. At the end of one year, Bill earned a total of \( \$ 150 \) interest in his two savings accounts. Which equation is sed to calculate \( x \), the amount Bill invested in his money market account? \( \begin{array}{l}(6000-x)(0.02)(1)+(x)(0.05)(1)=150 \\ (6000-x)(2)(1)+(x)(5)(1)=150 \\ (x)(0.02)(1)+(x)(0.05)(1)=6000 \\ (x)(2)(1)+(6000-x)(5)(1)=150 \\ (x)(0.02)(1)+(6000-x)(0.05)(1)=150\end{array} \)

A university alumni association invested part of \( \$ 22,000 \) in preferred stock that earns \( 8 \% \) annual simple interest, and the remainder in a municipal bond that earns \( 7 \% \). The amount of interest earned each year is \( \$ 1,610 \). How much was invested in each account? annual simple interest. The at \( 7 \% \$ \square \) at \( 8 \% \$ 0 \)

Suppose that in 1671, a man bought a diamond worth the equivalent of \( \$ 36 \). Suppose that the man had instead been able to put the equivalent of \( \$ 36 \) in a bank at \( 3 \% \) interest compounded continuously. What would that \( \$ 36 \) have been worth in 2003?

Art Neuner, an investor in real estate, bought an office condominium. The market value of the condo was \( \$ 315,000 \) with a \( 70 \% \) assessment rate. Art feels that his return should be \( 12 \% \) per month on his investment after all expenses. The tax rate is \( \$ 31.50 \) per \( \$ 1,000 \). Art estimates it will cost \( \$ 250 \) per month to cover general repairs, insurance, and so on. He pays a \( \$ 120 \) condo fee per month. All utilitles and heat are the responsibility of the tenant. Calculate the monthly rent for Art. (Round your Intermedlate calculations and final answer to the nearest cent.) Monthly rent
