A group of coworkers decided to buy their boss and $400 birthday gift, and to split the cost equally among themselves. When three of the coworkers decided not to contribute, those remaining still divided the $400 birthday gift equally, but each coworker's share of the cost increased by $30. How many coworkers were in the group originally?
Can anyone please help me to understand how to make equation of this kind of question.
