A company starts to track the numbers of phone calls received each month. Information about the number of phone calls the company received the first three months of tracking is listed below. During the first month, the company received 4,264 phone calls During the second month, the company received 25% more phone calls than in the first month. During the third month, the company received 6,396 phone calls. What was the percent increase in the number of phone calls from the second month to the third month.

20% has been increased in the number of phone calls from the second month to the third month.

Step-by-step explanation:

Given that,

In the first month, the company received 4,264 phone calls.

In the second month, the company received 25% more phone calls than in the first month.

Therefore, in the second month, the number of phone calls received by the company is 4264 plus 25% of 4264.

⇒ 4264 + (25/100) × 4264

⇒ 4264 + (0.25 × 4264)

⇒ 4264 + 1066

⇒ 5330 phone calls

The number of phone calls received in the second month is 5330.

In the third month, the company received 6396 phone calls.

To find the percent increase from 2nd to 3rd month :

Use the percentage increase formula,

Percentage increase = ((Higher value - lower value) / lower value) × 100

⇒ ((6396 - 5330) / 5330) × 100

⇒ (1066 / 5330) × 100

⇒ 0.2× 100

⇒ 20%

Therefore, the percentage increase in the number of phone calls from the second month to the third month is 20%
