Alice is determining the total amount of punch needed based on the number of servings she will need for an event next month. The graph below shows the number of servings based on the amount of punch.

Question

What is the unit rate of the graph?
A.
10 fluid ounces per serving
B.
0.2 fluid ounce per serving
C.
5 fluid ounces per serving
D.
1 fluid ounce per serving

The dot ends in 100,20

Answer 1

To find the unit rate from the graph, we can use the coordinates of the point given, which is (100, 20).

Here, the x-coordinate (100) represents the amount of punch in fluid ounces, and the y-coordinate (20) represents the number of servings.

To find the unit rate (the amount of punch per serving), we can calculate it as follows:

$$\text{Unit Rate}=\frac{\text{Amount of Punch (fluid ounces)}}{\text{Number of Servings}}=\frac{100\text{ fluid ounces}}{20\text{ servings}}$$

Calculating this gives:

$$\text{Unit Rate}=\frac{100}{20}=5\text{ fluid ounces per serving}$$

Therefore, the correct answer is:

C. 5 fluid ounces per serving.
