37. The Surrey County board of supervisors has agreed to fund an ambitious project that will “spend money now to save much more money in the future.” A total of $16.2 million will be awarded to the Green Corporation for energy improvements in 40 buildings, 27 parks, and 37 traffic intersections. These improvements include lighting upgrades, solar hot water collectors, more efficient heating/cooling systems, and light-emitting diodes for traffic signals. Bonds paying 5%

per year over the next 18 years will be used to pay for these improvements. If the annual savings fail to average

$3 million, Green Corporation will reimburse the county the difference. Will Green Corporation need to pay any money to the county? If so, how much? (4.7)
