this particular office machine. A new machine was
purchase for the cost of $3000.00. The maintenance
cost for the new machine is $0.50 per hour. How many
weeks will it take for the savings on maintenance cost
to pay for the new machine.

The new machine saves you 1.50 per hour. It costs 3000, so it will take 3000 / 1.5 = 2000 hours to break even.

Answer 2
