Question
The graph shows the cost of T-shirts at a local score.
A sign in the store window advertises 3 t-shirts for $16.50. Which coordinate pair shows the unit rate for the t-shirt sale?
Responses
A (0, 0)(0, 0)
B (1, 5.5)(1, 5.5)
C (2, 11)(2, 11)
D (3, 16.5)(3, 16.5)

The unit rate is the cost per unit. In this case, it is the cost per t-shirt. From the graph, we can see that at point D, the cost is $16.50 and the number of t-shirts is 3. Therefore, the coordinate pair (3, 16.5) shows the unit rate for the t-shirt sale. So, the correct answer is D.
are you sure that is the answer
Apologies for the confusion. I made a mistake in my previous response.
To find the unit rate for the t-shirt sale, we need to divide the total cost by the number of t-shirts. In this case, the total cost is $16.50 and the number of t-shirts is 3.
Therefore, the unit rate for the t-shirt sale is $16.50 / 3 = $5.50.
So, the correct answer is B, (1, 5.5).
To find the unit rate for the t-shirt sale, we need to determine how much 1 t-shirt costs.
From the graph, we can see that the x-axis represents the number of t-shirts and the y-axis represents the cost.
The sign in the store window advertises 3 t-shirts for $16.50. This means that the cost of 3 t-shirts is $16.50.
To find the cost of 1 t-shirt, we divide the total cost by the number of t-shirts. So, the unit rate for the t-shirt sale is $16.50 ÷ 3.
Simplifying this division, we get $5.50.
Therefore, the coordinate pair that represents the unit rate for the t-shirt sale is (1, 5.5).
The correct answer is B.
