Question

On​ Monday, a museum had 100 visitors. On​ Tuesday, it had 140 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

40% and 196

Explanation:

The computation of the number of people visit the museum on wednesday is shown below:

Given that

On monday, the visitors are 100

And, on tuesday, the visitors are 140

Now the percentage change would be

= (140 - 100) ÷ (100) × 100

= 40%

Now the visitors as on wednesday is

= 140 + 140 × 0.40

= 140 + 56

= 196
