Question

The number of people that belong to a certain social website is 412 and growing at a rate of 5% every month. How many members will there be in 9 months? Enter your answer in the box. Round to the nearest whole number.

Answer 1

Initial number of the people that belong to a certain social website is 412. It is growing at a rate of 5% every month. It means that every month the number of people is growing 1.05 times. We can calculate how many of them will there be in 9 months: 412 * 1.05^9 = 412 * 1.55 = 638.6. When we round to the nearest whole number: there will be 369 members.

Answer 2

Answer:639

Step-by-step explanation:

The equation for exponential growth is: initial amount( 1 + rate in decimal form)^time

So we put in our numbers and it is:  412( 1 + 0.5) ^ 9 = 639 (rounded)
