Question

At 10 a.m., there were 12 people in a swimming pool. At 11 a.m., there were 27 people in the pool.



What was the percent of increase in the number of people in the swimming pool from 10 a.m. to 11 a.m.?

Answer 1

So, It doubled to 24, which means it is 200%

then to get 27, we need to add on 3 out of 12 people which is the same as 1 out of 4 people which equals 25%

So what is 200+25?
Use a calculator if it's easier to figure out that way :)

Answer 2

225

Answer 3

15 more people came at 11:00 so 15
