(b) when did the number of visitors have the greatest decrease?
\bigcirc thursday to friday
\bigcirc friday to saturday
\bigcirc saturday to sunday
\bigcirc sunday to monday

Explanation:

Step1: Identify daily visitor counts

From the graph:
Thursday: 330, Friday: 300, Saturday: 305, Sunday: 320, Monday: 335, Tuesday: 325

Step2: Find maximum visitor count

Compare all values: $335 > 330 > 325 > 320 > 305 > 300$

Step3: Calculate daily changes

Thursday to Friday: $300 - 330 = -30$ (decrease of 30)
Friday to Saturday: $305 - 300 = +5$ (increase of 5)
Saturday to Sunday: $320 - 305 = +15$ (increase of 15)
Sunday to Monday: $335 - 320 = +15$ (increase of 15)
Monday to Tuesday: $325 - 335 = -10$ (decrease of 10)

Step4: Identify largest decrease

Compare decrease values: $30 > 10$

Answer:

(a) 335 visitors
(b) Thursday to Friday
