Simple Interest formula is : $I=P*r*t$ , where I = Amount of interest, P= Principal amount, r = rate of interest in decimal and t = time duration in year.

Given in the question that, P = $800 and r = $4\frac{3}{4}$ % = 4.75% = 0.0475

<u>a.</u> For t = $\frac{1}{2}$ year ....

$I= 800*0.0475*\frac{1}{2}\\ \\ I= 19$

So, Jada will receive $19 interest at the end of 1/2 year.

<u>b.</u> For t = 1 year ....

$I= 800*0.0475*1\\ \\ I= 38$

So, Jada will receive $38 interest at the end of 1 year.
