Juan Martin and Melanie have a new grandson. How much money should they invest now so that he will have \( \$ 74,000 \) for his college education in 18 years? The money is invested at \( 6.35 \% \) compounded annually.

How much money must you invest now at \( 4.6 \% \) interest compounded continuously in order to have \( \$ 10,000 \) at the end of 6 years?

21.- Un fabricante vende un producto a \( \$ 5,00 \) por unidad, vendiendo todo lo que produce, el costo fijo es \( \$ 3.000 \) y el variable por unidad es de \( 15 / 4 \) de q. La producción y el ingreso total en el punto de equilibrio es: a. 200 unidades y \( \$ 1.000 \) b. Ninguna es correcta (demostrar) I. c. 2.400 unidades y \( \$ 12.000 \) d. 500 unidades y \( \$ 2.000 \)

Find the time required for an investment of 3,000 dollars to grow to 12,000 dollars at an interest rate of \( 7 \% \) per year, compounded monthly. Give your answer accurate to 2 decimal places. \( \square \) years.

Suppose you have \( \$ 15,000 \) to invest. Which of the two rates would yield the larger amount in 3 years: \( 8 \% \) compounded daily or \( 7.90 \% \) compounded continuously? Which of the two rates would yield the larger amount in 3 years? \( 8 \% \) compounded daily \( 7.90 \% \) compounded continuously
