Ett lån på 20000 kr ska amorteras en gång per kvartal, d.v.s. var tredje månad, und ett år. Årsrāntesatsen är 8 \%. Kvartalsränta betalas samtidigt med amorteringama. a) Hur stor blir den första amorteringen? b) Hur stor blir den första ränteinbetalningen? De senaste åren har KPI förändrats enligt nedansuaende tabell.

PC GLOBAL está evaluando dos proyectos de inversión para el próximo año. El proyecto A requiere una inversión inicial de \( \$ 100.000 .000 \) y generará retornos anuales de \( \$ 30.000 .000 \) durante 4 años. El proyecto B requiere una inversión inicial de \( \$ 120.000 .000 \) y generará retornos anuales de \( \$ 35.000 .000 \) durante el mismo periodo. Si la tasa de descuento es del \( 15 \% \), calculâ el Valor Actual Neto (VAN) de cada proyecto y determina cuál sería la mejor opción de inversión.

The neighbourhood bookstore sells novels for \( \$ 15 \) per unit. The cost to purchase one book is \( \$ 13 \). The store has fixed costs per month of \( \$ 1900 \). The store estimates that they can sell 2100 books each month. (a) Compute the break-even point in units. (b) Compute the break-even point in sales dollars. (c) Compute the break-even point as a percent of capacity. (a) The break-even point in units is 950 books. (Simplify your answer.) (b) The break-even point in sales dollars is \( \$ 14250 \). (Simplify your answer.) (c) The break-even point as a percent of capacity is \( \square \% \). (Round to two decimal places as needed.) - 3 .

An OB/GYN physician in private practice knows her malpractice insurance will be \( \$ 90,000 \) and is due in one year. How much should she deposit into an account each month if that account has an annual rate of \( 3.3 \% \) compounded monthly and she wishes to pay it in full knowing that the insurance company drops the price by \( 2 \% \) if paid in full? Round your answer to two decimal places. Do not include the \( \$ \) sign in your answer. Hint: Lower the price by \( 2 \% \) as she is planning on paying in full.

Suppose that \( \$ 59,000 \) is invested at \( 4 \frac{1}{2} \% \) interest, compounded quarterly. a) Find the function for the amount to which the investment grows after \( t \) years. b) Find the amount of money in the account at \( t=0,2,6 \), and 10 years. a) The function for the amount to which the investment grows after t years is \( \mathrm{A}(\mathrm{t})= \) (Simplify your answer. Type an expression using t as the variable.) b) Find the amount of money in the account at \( \mathrm{t}=0,2,6 \), and 10 years. The amount of money in the account at \( \mathrm{t}=0 \) years is \( \$ \square \). (Round to the nearest dollar as needed.) The amount of money in the account at \( \mathrm{t}=2 \) years is \( \$ \square \). (Round to the nearest dollar as needed.)
