Question

On​ Monday, a museum had 400 visitors. On​ Tuesday, it had 780 visitors. Estimate the percent change in the number of visitors to the museum. Use pencil and paper. Estimate how many people would have to visit the museum on Wednesday to have the same estimated percent change between Tuesday and Wednesday as between Monday and Tuesday

Answer 1

Alright, lets get started.

Numbers of visitors on Monday = 400

Numbers of visitors on Tuesday = 780

So, percentage change = $\frac{780-400}{400}*100$

So, percentage change  = $\frac{380}{400} *100$

So, percentage change = 95 %    :    Answer

If same estimated percentage increase on next day also, means on Wednesday, the number of visitor will be = $780+ 780*95$%

So,number of visitors on Wednesday = $780 + 741$

Number of visitors on Wednesday = 1521     :    Answer
