A town's total allowance for policeman's wages and benefits in a new budget is 600,000. If wages are calculated at 40,000 per policeman and benefits at 20,000 per policeman, write an equation whose solution is the number of policemen the town can employ if they spend their whole budget.

• 20,000 + 40,000x = 600,000

• 40,000=600,000

• 60,000x=600,000

• 600,000x - 40,000x = 20,000
