Answer:

B. 0.86 inch

Step-by-step explanation:

The thickness of a brand new one-dollar bill


=4.3*10^(-3)\text{ inch}

If there are 200 brand new one-dollar bills, the thickness will be:


\begin{gathered} =200*4.3*10^(-3)\text{ inch} \\ =860*10^(-3) \\ =0.86\text{ inch} \end{gathered}

A stack of 200 bills would be 0.86 inches thick.
