Final answer:
To find the total number of visitors to the art museum for the week, divide the Sunday visitor count (285) by 0.2 (which represents 20%) and then multiply by 100 to get the total, which is 1,425 visitors.
Step-by-step explanation:
The question involves finding the total number of visitors to the art museum based on the percentage given for a single day. If 285 visitors correspond to 20% of the total visitors for the week, we can determine the full 100% by dividing the number of visitors (285) by the percentage they represent (20%) and then multiplying by 100 to find the total number of visitors.
Step-by-Step Calculation:
Divide the number of visitors for Sunday by the decimal (285 / 0.2).
Multiply the result from step 2 by 100 to find the total number of visitors.
After performing these calculations, we find that the total number of visitors for the week is 1,425.
