Answer:
495,594
Explanation:
1. Multiply Richmond's population by 80%. This gives you the number of people who have moved into the town since Wesley moved there.
275,330 x 80% = 220,264
2. Add this back to the original population. This gives you the new population.
275,330 + 220,264 = 495,594
3. The current population is 495,594
