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?(1 point)

To find the cost per serving, we need to determine the cost of each serving.

The difference in cost between 10 servings ($60) and 3 servings ($18) is $60 - $18 = $<<60-18=42>>42.
Therefore, the cost per serving is $42/10 servings = $<<42/10=4.20>>4.20/serving.
