The cost of constructing a roundabout in a lowtraffic residential neighborhood five years ago was $625,000. A civil engineer designing another one that is almost exactly the same estimates the cost today will be $740,000. (a) If the cost had increased only by the inflation rate over the fiveyears, what was the actual inflation rate per year? (b) What is the interest rate involved in this computation?
