Let's solve this tip calculation step by step.

1. The bill is **$90.87**. The task asks you to round the bill to the nearest dollar before calculating. So, we round **$90.87** to **$91**.
   
2. Now, calculate **20%** of this rounded amount:
   \[
   20\% \text{ of } 91 = 0.20 \times 91 = 18.20
   \]
   
So, the estimated tip is **approximately $18.20**.
