I'll give you a question, please answer with step-by-step reasoning process.
Every day, Bob logs 10 hours of work in his office. If he works for five days a week, calculate the total number of hours he logs in a month.

200
In a week, working 10 hours a day, Bob logs 10 * 5 = 50 hours.

After a month with 4 weeks, Bob logs 4 * 50 = 200 hours for his office working hours.

.

The answer is 200
