Answer 1

Edward's tea shop served 27 caffeinated teas during the lunchtime rush, as 90% of 30 is 27.

Step-by-step explanation:

The question asks how many caffeinated teas Edward's tea shop served during the lunchtime rush, given that 90% of the 30 teas served were caffeinated. To calculate the number of caffeinated teas, we need to find 90% of 30.

To do this, we can use the following steps:

1. Convert the percentage to a decimal by dividing by 100. So, 90% becomes 0.90.
2. Multiply the total number of teas (30) by the decimal percentage (0.90).
3. The result of this multiplication gives us the number of caffeinated teas.

After performing the calculation (30 x 0.90), we find that Edward's tea shop served 27 caffeinated teas during the lunchtime rush.
