To estimate the total number of plates in the restaurant, you can multiply the number of racks by the number of plates per rack.
19 racks × 37 plates per rack = 703 plates.
To find a suitable estimate, you can round the numbers:
- 19 can be rounded to 20.
- 37 can be rounded to 40.
Now, multiply the rounded values:
20 × 40 = 800.
So, the correct estimate is 800 plates.
