$(5$ points$)$ Mr$.$ Diaz is creating a college fund for his daughter. He plans to make $4-$yearly payments of $$7,000$ each with

the first payment deposited today on his daughter's $7^{th}$ birthday $($happy birthday!$)$ Assuming his daughter will need four

equal withdrawals from this account to pay for her education beginning when she is eighteen $($i$.$e$.18,19,20,21),$ how

much will she have on a yearly basis for her university career? Mr$.$ Diaz expects to earn a constant $10\%$ annual return

for the time interval of this problem.

Anural Deposit $=7000$

Number of Deposits $=4$

Annual Return $=10\%$

$(10$ points$)$ Given an interest rate of $10\%$ find the value of the missing payment in year$-5$ if the whole stream of

payments, inclusive of the missing payment is equal to $$3426\mathrm{.}47$
