On Monday, a museum had 400 visitors. On Tuesday, it had 780 visitors. Estimate the percent change in the number of visitors t

11Alexandr11 [23.1K]

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
