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 the worker earn before going on vacation?

Answer 1

The worker earns $10 per hour and works 10 hours a day, so the worker earns $10 x 10 = $100 per day.
The worker works for 10 days before the vacation, so the worker earns $100 x 10 = $1000 before going on vacation.
Therefore, the worker earns $1000 before going on vacation.
