The Autocar E3 refuse truck has an energy recovery system developed by Parker Hannifin LLC that is expected to reduce fuel consumption by 50%. Pressurized fluid flows from carbon fiber–reinforced accumulator tanks to two hydrostatic motors that propel the vehicle forward. The truck recharges the accumulators when it brakes.

The fuel cost for a regular refuse truck is $800 per month. How much can a private waste hauling company afford to spend on the recovery system, if it wants to recover its investment in 3 years at an interest rate of 12% per year?
