Question

Around 1,100 scientists live in Antarctica during the winter. In the summer that number increases to around 5,000 scientists. As the seasons change, what is the percent change in the number of scientists living in Antarctica?

Answer 1

Answer:

78%

Step-by-step explanation:

Given

Number of scientist that line in Antarctica during the winter = 1,100

Amount of scientist  in the summer = 5,000

Increment = 5000 - 1100

Increment  = 3900

percentage change = Increment/Original amount * 100

Percentage change = 3900/5000 * 100

Percentage change = 3900/50

Percentage change = 78%

Hence the percent change in the number of scientists living in Antarctica is 78%
