The Kims are hosting a catered dinner. The cost for 3 servings is $18. The cost for 10 servings is $60. What is the cost per serving?

Question

$ (?) per serving

Answer 1

To determine the cost per serving, we can find the average cost based on the servings.

From the information provided:

• For 3 servings, the total cost is $18.
• For 10 servings, the total cost is $60.

Now let's calculate the cost per serving for each case:

1. Cost per serving for 3 servings: \[ \text{Cost per serving} = \frac{\text{Total Cost}}{\text{Number of Servings}} = \frac{18}{3} = 6 \text{ dollars per serving} \]

2. Cost per serving for 10 servings: \[ \text{Cost per serving} = \frac{\text{Total Cost}}{\text{Number of Servings}} = \frac{60}{10} = 6 \text{ dollars per serving} \]

In both cases, the cost per serving is $6.

Thus, the cost per serving is $6 per serving.
