Czarina is working part time at a pastry shop baking cupcakes. If she works for 30 hours in one week on the average, how many hours a day does she work?

How many days does she work each week?

7 days

To find out how many hours a day Czarina works, we can divide the total number of hours she works in a week by the number of days she works.

Given that Czarina works for 30 hours in one week, we need to determine the number of days she works. Let's assume that she works a standard 7-day week.

To find the average number of hours per day, we divide the total number of hours (30) by the number of days.

Average hours per day = Total hours / Number of days

Average hours per day = 30 hours / 7 days

To calculate this, we can use a calculator or do the long division:

30 divided by 7 equals approximately 4.29

So, on average, Czarina works approximately 4.29 hours per day.

Since we're dealing with hours, we round this value to the nearest whole number. In this case, Czarina works approximately 4 hours per day.
