Achain saw requires 7 hours of assembly and a wood chipper 4 hours. a maximum of 84 hours of assembly time is available. the profit is $160 on a chain saw and $ 220 on a chipper. how many of each should be assembled for maximum profit?

0 and 21.

Step-by-step explanation:

Given that a  chain saw requires 7 hours of assembly and a wood chipper 4 hours. A maximum of 84 hours of assembly time is available.

Let X be the number of chain saw and Y no of chippers.

Then constraint is

total no of hours =84

i.e.

Our objective is to maximize total profit

We find that y fetches more profit

So total 84 hours if utilized for y, we can manufacture 21 with total profit

Instead if 12 units of chain saw produced profit would be 160(12) = 1820

very less than the amount 4840

So 21 units of chipper and no chain saw should be assembled.

0.50 , 0.75
