Question

last year, tea off served a total of 7,720 cups of chamomile tea to its customers. this year, the cafe served 11,194 cups. what is the percent of increase in the annual amount of chamomile tea served? %

Explanation:

Step1: Find the increase in cups

First, we need to find the difference between the number of cups served this year and last year. So we calculate \( 11194 - 7720 \).
\( 11194 - 7720 = 3474 \)

Step2: Calculate the percent increase

The formula for percent increase is \( \text{Percent Increase} = \frac{\text{Increase}}{\text{Original Amount}} \times 100\% \). Here, the original amount is the number of cups served last year (7720), and the increase is 3474. So we substitute these values into the formula:
\( \text{Percent Increase} = \frac{3474}{7720} \times 100\% \)
First, calculate \( \frac{3474}{7720} \approx 0.45 \)
Then multiply by 100%: \( 0.45\times 100\% = 45\% \)

Answer:

45%
