Final answer:
The labor cost for making the dish is $30.
Step-by-step explanation:
The labor cost for the dish is $40 per hour. If it takes 45 minutes to make the dish, we need to calculate the cost for that duration.
First, we convert 45 minutes to hours. 45 minutes is equal to 45/60 = 0.75 hours.
To find the labor cost for 0.75 hours, we multiply the labor cost per hour ($40) by the duration in hours (0.75).
Therefore, the labor cost for this particular dish is $40 * 0.75 = $30.
