Rita has 40 green bottles and 10 red bottles.

What percentage of the bottles are red?

Answer: 20 percent

Step-by-step explanation:

Total number of bottles is 40 + 10 = 50 bottles

Given that there are 10 red bottles, to find the percentage, we divide the number of red bottles by total number of bottles then multiply by 100

Therefore, % of red bottles = 10/50 * 100

=20.
