Jessica deposited a $2,850.28 paycheck, a $641 stock dividend check, a $75 rebate check, and $450 cash into her checking account. Her original account balance was $120.12.
Assuming the checks clear, how much was in her account after the deposit was made?

Six years ago, an 80-kw diesel electric set cost $160,000. the cost index for this class of equipment six years ago was 187 and is now 194. the cost-capacity factor is 0.6. the plant engineering staff is considering a 120-kw unit of the same general design to power a small isolated plant. assume we want to add a precompressor, which (when isolated and estimated separately) currently costs $13291. determine the total cost of the 120-kw unit.
