Can someone show me this solution in Excel?

You are 25 years old. You are willing to work for the next thirty years at which time you want to retire and serve missions until you are magically twinkled at the age of 75, conspicuously the age of a tree. Who knew. You expect to need $5,000 per month while you are retired. Assume an interest rate of 5% compounded monthly. How much would you need to deposit every month during your working years so that you can pull this off?

What is the value of an annuity that pays $1,000 per month for 2 years at 7%. What is the value of this annuity if its calculated as an annuity due?
