problem_activity: Task
A town's total allocation for firefighter's wages and beneﬁts in a new budget is \$600,000. If wages are calculated at \$40,000 per firefighter and beneﬁts at \$20,000 per firefighter, write an equation whose solution is the number of firefighters the town can employ if they spend their whole budget. Solve the equation.
