If the teacher buys 2 et of markers, the total cost will be 4 dollars, and if the teacher buys 3 et of markers, the total cost will be 7 dollars.

The relationship between the number of et of markers bought by the teacher (x) and the total cost of the markers (y) can be represented by the following linear equation:

y = 3x - 2

This equation shows that the cost of the markers (y) is equal to the number of et of markers bought (x) multiplied by the cost per et ($3) minus the discount from the coupon ($2).

We can represent this relationship in a table as follows:

x (et of markers) y (total cost)

1 1 * 3 - 2 = 1

2 2 * 3 - 2 = 4

3 3 * 3 - 2 = 7

4 4 * 3 - 2 = 10

5 5 * 3 - 2 = 13

This table shows that as the number of et of markers increases, the total cost also increases by a constant amount of $3 for each additional et.

For example, if the teacher buys 2 et of markers, the total cost will be 4 dollars, and if the teacher buys 3 et of markers, the total cost will be 7 dollars.

Overall, the table illustrates the linear relationship between the number of et of markers bought and the total cost of the markers, with the total cost being equal to the number of et of markers bought multiplied by the cost per et minus the discount from the coupon.
