Final answer:
To estimate the percent change, use the formula (New Value - Old Value) / Old Value x 100%. To estimate the number of visitors on Wednesday to have the same percent change, use the formula New Value = Old Value + (Old Value x Percent Change / 100%).
Step-by-step explanation:
To estimate the percent change in the number of visitors to the museum, you can use the formula:
Percent Change = (New Value - Old Value) / Old Value x 100%.
Using this formula, we can calculate the estimated percent change:
Percent Change = (380 - 300) / 300 x 100% = 26.67%.
Now, to estimate how many people would have to visit the museum on Wednesday to have the same estimated percent change as between Monday and Tuesday, you can use the formula:
New Value = Old Value + (Old Value x Percent Change / 100%).
Plugging in the values, we get:
New Value = 380 + (380 x 26.67% / 100%) = 480.4 visitors (approximately).
