Question

based on the data collected, if the store has been open 7 hours, which scenario is most likely to be true? after 1/2 hour, 1 customer had been in the store. after 6 hours, 129 customers had been in the store. after 7 hours, 175 customers had been in the store. after 8.5 hours, 225 customers had been in the store.

Explanation:

Step1: Analyze each option

• Option1: At \(x = 0.5\), from the graph, the number of customers is not \(1\).
• Option2: At \(x = 6\), from the graph, the number of customers is \(125\) (since each grid is \(25\) and \(5\times25=125\) for \(x = 6\)), not \(129\).
• Option3: At \(x = 7\), from the graph, the point is at \(175\) ( \(7\times25 = 175\)).
• Option4: At \(x=8.5\), from the graph, the number of customers is more than \(225\).

Answer:

After 7 hours, 175 customers had been in the store.
