I need answer ASAP

Karen Powell makes three different silverware - spoons, forks and knives. Each unit (dozen) of spoon gives her a profit of $11.50, forks of $18 and knives of $17.50. She has 183 hours of machine time, 250 hours of labor and 185 pounds of steel. It takes her 4 hours of machine time, 4 hours of labor time and 3 pounds of steels to make one unit of spoons. Each unit of forks take 4 hours of machine time, 9 hours of labor time and 2 pounds of steel, while knives take 5 hours of machine time, 5 hours of labor and 4 pounds of steel. It is also found that she should make at least 15 units of spoons in the process.

Solve the following linear program

The solution is x1 = [ Select ] ["24", "15", "0", "7", "12"] , x2 = [ Select ] ["22", "48.0", "16.2", "12.3", "13.4"] , x3 = [ Select ] ["21.2", "48.7", "10.4", "16.7", "13.9"] , with an objective value of [ Select ] ["$656.60", "$1024.45", "$792.22", "$756.23", "$622.00"] .

The resources that are used up are: [ Select ] ["labor hours and materials (steel)", "none are used up", "all are used up", "machine time and materials (steel)", "machine time and labor hours"]

If it was decided that at least 20 units of spoons should be made instead of 15, what impact does it have on profits? [ Select ] ["a decrease in profit of $34.50", "an increase in profit of $46.00", "a decrease in profit of $12.50", "there was no change in profit", "an increase in profit of $13.75"]
