(b) when did the number of visitors have the greatest increase?

Explanation:

Step1: Identify the lowest point on the graph

By observing the line - graph, the lowest value on the vertical - axis (number of visitors) is 290, which occurs on Tuesday.

Step2: Calculate the increase between each pair of days

Thursday to Friday: \(330 - 300=30\); Friday to Saturday: \(315 - 330=- 15\) (decrease); Saturday to Sunday: \(305 - 315=-10\) (decrease); Sunday to Monday: \(310 - 305 = 5\). The greatest increase is from Thursday to Friday.

Answer:

(a) 290
(b) Thursday to Friday
