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.

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
