We need to estimate the sum:


45.86+54.14

In order to do so, we first round each term to the nearest integer. Then we add them.

We have:


\begin{gathered} 45.86\cong46\text{ (because 0.86>0.50)} \\ \\ 54.14\cong54\text{ (because 0.14<0.50)} \end{gathered}

Then, we can estimate the sum to be:


45.86+54.14\cong46+54=100

Therefore, option C is correct.
