An assembly line produces 20 items per hour. If the line runs 24 hours per day, 7 days per week, how many items are made by this machine in one month? (Assume 30 days/month)

A. 3,360
B. 14,400
C. 13,440
D. 100,800

Answer :

To solve this problem, we need to calculate how many items are produced by the assembly line in one month. Let's break it down step by step:

1. Calculate the number of items produced per day:
- The assembly line produces 20 items per hour.
- The line runs 24 hours per day.
- Therefore, the number of items produced in one day is:
[tex]\[ 20 \text{ items/hour} \times 24 \text{ hours/day} = 480 \text{ items/day} \][/tex]

2. Calculate the number of items produced in one month:
- We assume there are 30 days in a month.
- The assembly line produces 480 items every day.
- Therefore, the number of items produced in one month is:
[tex]\[ 480 \text{ items/day} \times 30 \text{ days/month} = 14,400 \text{ items/month} \][/tex]

So, the total number of items produced in one month is 14,400.

The correct answer is B. 14,400.
