Solving A = Pet for P, we obtain P=Ae" which is the present value of the amount A due in t years if money earns interest at an annual nominal rate r compounded continuously. For the function P = 6,000 0.04, in how many years will the $6,000 be due in order for its present value to be $4,000? In years, the $6,000 will be due in order for its present value to be $4,000. (Type an integer or decimal rounded to the nearest hundredth as needed.)

Money is transferred continuously into an account at the constant rate of $80,000 per year. The account earns interest at the annual rate of 5% compounded continuously. How much will be in the account at the end of 10 years? Round to the nearest dollar.

A principal amount of $1500 is placed into a savings account with an APR of 2.55% simple interest for 10 years. The same principal is placed into a savings account with an APR of 3.15% compounded continuously for 7 years. How do I solve this equation? And what formulas should I use? Please show me step by step.

Two numbers are greater than 10 but less than 40. Their GCF is 17. What are the two numbers?
