This year, druehl, inc., will produce 57 comma 60057,600 hot water heaters at its plant in delaware, in order to meet expected global demand. to accomplish this, each laborer at the plant will work 160160 hours per month. if the labor productivity at the plant is 0.150.15 hot water heaters per labor hour, how many laborers are employed at the plant?

We know that:

rate = 0.15 heaters /labor  hour

labourer time = 160 hours / month

goal = 57,600 heaters / year

We can solve this problem by simply looking at which ratios will cancel out the units:

number of labourers = (57,600 heaters/year) / [(0.15 heaters /labor  hour) * (160 hours/month) * (12 month/year)

number of labourers = 200

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

it is x equals 3   plese mark me really need it
