Question 4 Use the formula for present value of money to calculate the amount you need to invest now in one lump sum in order to have \( \$ 25,000 \) after 10 years with an APR of \( 11 \% \) compounded quarterly. Round your answer to the nearest cent, if necessary.

a) \( \sqrt{3} \times \sqrt{5} \)

The Gray family wants to save money to travel the world. They purchase an annuity with a yearly payment of \( \$ 639 \) that earns \( 4.8 \% \) interest, compounded annually. Payments will be made at the end of each year. Find the total value of the annuity in 11 years. Do not round any intermediate computations, and round your final answer to the nearest cent. If necessary, refer to the list of financial formulas.

The total cost of an item including sales tax is directly proportional to its price. If the total cost of a \( \$ 25 \) item is \( \$ 25.75 \), what is the total cost on a \( \$ 60 \) item?
