Question
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)
$
per serving
$6 per serving
To find the cost per serving, we can first calculate the slope of the line passing through the two points (3, $18) and (10, $60).
slope = (change in cost) / (change in servings)
slope = ($60 - $18) / (10 - 3)
slope = $42 / 7
slope = $6 per serving
Therefore, the cost per serving is $6.
