Answer 1

Given:

First month = 4,264 phone calls.

Second month = 25% more calls than the first month.

Third month = 6393 phone calls.

To Find:

The percentage increased from the second month to the third month.

Solution

Find the number of calls in the second month:

$\text{Increase in number of calls } = 25\% \text{ of } 4264$

$\text{Increase in number of calls }= 0.25 \times 4264$

$\text{Increase in number of calls }= 1066$

$\text{Number of calls } = 4264 + 1066$

$\text{Number of calls } = 5330$

Find the increase from the second month to the third month:

$\text{Increase } = 6393 - 5330$

$\text{Increase } = 1063$

Find the percentage increased:

$\text{Percentage Increased } = \dfrac{\text{Increase}}{\text{Original Value}} \times 100$

$\text{Percentage Increased } = \dfrac{1063}{5330} \times 100$

$\text{Percentage Increased } = 19.9\%$

Answer: There is a 19.9% increase from the second month to the third month.
