A farmer raises goats and cows. Each goat requires 400 square feet of grazing area and
each cow requires 1200 square feet of grazing
area. The farmer has 36,000 square feet of
grazing area. Write a function to represent
the combination of goats and cows the farmer
can raise. If the farmer raises only cows, how
many can he raise? If the farmer raises only
goats, how many can he raise?

I'm guessing

Step-by-step explanation:

My calculations assume at least 456

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
