It takes melissa eight hours to produce a bushel of corn and two hours to wash and polish a car. it takes greg six hours to produce a bushel of corn and one hour to wash and polish a car. if greg and melissa each work 48 hours in one week and produce only the good for which they have the comparative advantage, how much corn is produced and how many cars are washed in total?

0 bushels of corn 72 cars

Step-by-step explanation:

Melissa produces at the rate:

1 bushel of corn  per 8 hrs

Wash and polish a car per  2 hrs

She will wash and polish  cars  because she has the comparative advantage of requiring less time  ( 2 vs 8 hours)

Greg also will only wash and polish cars because he requires 8 hours to produce a bushel of corn vs 1 hour to wash and polish a car

Therefore  both Melissa and Greg  will wash and polish cars in the 48 hours:

Melissa will work on 24 cars since she requres 2 hours and Greg will produce 48 cars since he needs only an hour per job.

The total corn produced will be 0 bushels and  72 cars ( 24 + 48 )

the 3rd on is correct

step-by-step explanation:

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
