Answer:
Weeks 1 2 3 4 5
Tickets Sold (thousands) 800 400 200 100 50
is the right answer
Step-by-step explanation:
The x-values increase by one, so the data points are consecutive.
Find the ratio of the first two y-values in the table, 800 and 400. To find the multiple that changes 800 into 400, divide the second value by the first value.
Similarly, find the common ratio between each of the ordered pairs with consecutive x-values from the table.
The ratios between each pair of y-values is the same. Therefore, the relationship changes by a constant multiple, and this table represents an exponential relationship.
