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

El número de bacterias de un cultivo es de 250 , si estas se triplican por hora ¿Cuántas bacterias habrá en 5,10 horas y en uno y dos dias? 3. Una persona invierte \( \$ 25000 \) en un banco con un interés mensual del \( 4 \% \), ¿Cuánto dinero tendrá después de \( 3,9,12 \) y 18 meses? 4.

\( 3 i l l \) 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? \( \begin{array}{l}(6000-x)(0.02)(1)+(x)(0.05)(1)=150 \\ (6000-x)(2)(1)+(x)(5)(1)=150 \\ (x)(0.02)(1)+(x)(0.05)(1)=6000 \\ (x)(2)(1)+(6000-x)(5)(1)=150 \\ (x)(0.02)(1)+(6000-x)(0.05)(1)=150\end{array} \)
