Answer:

Option D. \$83.75  

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

A=P(1+\frac{r}{n})^{nt}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

t=30\ years\\ P=\$187.45*0.10=\$18.745\\ r=0.05\\n=12  

substitute in the formula above  

A=\$18.745(1+\frac{0.05}{12})^{12*30}=\$83.75
