Anew equipment has been proposed by engineers to increase the productivity of a certain manual welding operation. the investment cost is $25,000, and the equipment will have a market value of $5,000 at the end of a study period of five years. increased productivity attributable to the equipment will amount to $10,000 per year after operating costs have been subtracted from the revenue generated by the additional production. if marr is 10%, is investing in this equipment feasible? use annual worth method.

What outputs a and b (in millions of dollars per year) should the two industries generate to satisfy the demand? you may be tempted to say 1,000 and 780, respectively, but things are not quite as simple as that. we have to take into account the interindustry demand as well. let us say that industry a produces electricity. of course, producing almost any product will require electric power. suppose that industry b needs 1o¢ worth of electricity for each $1 of output b produces and that industry a needs 20¢ worth of b's products for each $1 of output a produces?

If a stadium has 15,000 seats sold at 10.00, 12.50 and 15.00 equally distributed in three sections how much can be made of the stadium sells out
