A worker in a factory earns $10 an hour. The worker works 10 hours a day for 10 days straight before a vacation. How much money did the worker earn before going on vacation?

To calculate the total earnings, we need to multiply the worker's hourly rate by the number of hours worked per day for the number of days worked.

Total earnings = $10/hour * 10 hours/day * 10 days = $1000.

So, the worker earned $1000 before going on vacation.

The correct option is 10^3.

The worker earns $10 per hour and works 10 hours a day for 10 days straight before going on vacation.

To calculate the total earnings, we can multiply the worker's hourly rate by the total number of hours worked:

$10/hour * 10 hours/day * 10 days = $1000.

Therefore, the worker earned $1000 before going on vacation, which is equivalent to 10^3 (10 to the power of 3).
