Q$1.$ In the sheet Q$1$ you will find a partially$-$filled worksheet. The traveler invests $1,000$ dollars and leaves it in the bank account that pays $10\%$ per year. Suppose now that the traveler intends to retire in $15$ years and travel all over the world after his retirement. And suppose he plans to make $15$ annual deposits of $$1,000,$ with the first deposit made in T$0($today$)$ and each succeeding deposit made at the end of years $1,2,$dots,$14$

$1.$a$.(7$ points for the final answer only, no partial credit$)$ First, use the FV function to calculate the future value of all these deposits at the end of year $15$ which tells us how much the traveler will have accumulated in the account. Do this in cell B$5$ and we want a positive number in this cell.

$1.$b$.(10$ points$)$ Second, create a two$-$way$-$table, and show how does the previous answer change when the amount deposited $($in $1$a$.$ it is $1000$ dollars$)$ varies to $200,400,600,800,1000,1200,1400,1600,1800,2000$ dollars, and when the interest rate $($in $1$ a$.$ it is $10\%)$ varies to $,14\%,15\%$
