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.

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
