The Public Service Board (PSB) awarded two contracts worth a combined $3.07 million to increase the depth of a retention basin and reconstruct a spillway that was severely damaged in a flood 2 years ago. The PSB president stated that, surprisingly, the bids were $1,150,000 lower than PSB engineers estimated. If the projects are assumed to have a 20- year life, what is the annual worth of the savings at an interest rate of 5% per year?
What will be an ideal response?
A = 1,150,000(A/P,5%,20)
= 1,150,000(0.08024)
= $92,276
