3. Here we use the formula

$A = P ( 1 + \frac{r}{n} )^ {nt}$

And we have the following values given

$P = $23400, r = 3%=0.03,n =2, t=10 years$

So we will get

$A = 23400(1+ \frac{0.03}{2} )^{2*10}
\\
A = 23400( \frac{2.03}{2} )^{20} = $31516.52$

Question 4.

In this question , we have

$P = $2310, R = 3.5% = 0.035 ,
\\
Number \ of \ days \ from \ april \12 to July \ 5 = 30+31+23 = 84 days$

$A = 2310(1+ \frac{0.035}{365})^{84} = $2328.68$

Interest is the difference of amount and principal, that is

$I = 2328.68-2310 = $18.68$
