Question

in 2015, an app had 900 million monthly active users worldwide. by 2021, this number had increased 185.2%. to the nearest million, what was the number of the app’s monthly active users worldwide in 2021?

the number of the app’s monthly active users worldwide in 2021 was \boxed{} million.
(round to the nearest million as needed.)

Explanation:

Step1: Calculate the increase amount

First, we need to find out how much the number of users has increased. The increase percentage is 185.2%, and the original number of users is 900 million. To find the increase, we calculate \( 900\times185.2\% \). Converting the percentage to a decimal, \( 185.2\% = 1.852 \), so the increase is \( 900\times1.852 = 1666.8 \) million.

Step2: Calculate the total number of users in 2021

The total number of users in 2021 is the original number plus the increase. So we add 900 million to the increase we just calculated: \( 900 + 1666.8 = 2566.8 \) million.

Step3: Round to the nearest million

Rounding 2566.8 to the nearest million gives us 2567 (since the decimal part 0.8 is greater than or equal to 0.5, we round up the whole number part).

Answer:

2567
