Five projects have been identified for possible implementation by a company that makes dry ice blasters-machines that propel tiny dry ice pellets at supersonic speeds so they fl ash-freeze and then lift grime, paint, rust, mold, asphalt, and other contaminants off in-place machines and a wide range of surfaces. The total present worth of the initial investment for each project is shown. Determine which bundles are possible, provided the budget limitation is
(a) $34,000
(b) $45,000.
