YOU and your BEST FRIEND just graduated from college. You both went to the same college and majored in the same field. You both started working at age $22$ in the same workplace. Each of you decided upon a different course of action for your respective retirement plans. Assuming each plan earned $14\%$ and both of you decided to retire at age $62,$ calculate the earnings each plan generated.

Upon the advice of your Personal Finance professor $($hint$,$ hint$),$ at the age of $22$ years old... YOU began immediately putting $$7,000$ per year in an individual retirement account $($IRA$)$ and $$23,000$ per year in a $401$K$.$ In total you put in $$30,000$ each year. You contributed for a total of $30$ years. After $30$ years, you made no further contributions into the account.

Your BEST friend did not contribute to their retirement accounts until they turned $30$ years old, even though you both worked in the same place and received the same plans. They had planned to simply invest $$7000$ and $$23,000$ each year for the remaining years until they retired at age $62.$ In total they put in $$30,000$ each year until age $62.$

$17)$ How much did You contribute OUT of pocket in total into your plan?

$18)$How much did your BEST FRIEND contribute OUT of pocket in total into their plan?

$19)$How much did You accumulate in Your retirement account with interest?

I would like help with $19$ and $17$ please!
