Break even point is where all the expense is already covered by the revenue. In this case, the expense would be the stand ($75,000) and the lemon+sugar+water ( $1.25 per glass). The revenue comes from lemonade($30/glass). Then the equation would be:
$30 * glass of lemonade= $75,000 + $1.25 * glass of lemonade
($30-$1.25) * glass of lemonade= $75,000
glass of lemonade= 2608.7
Rectanglearea=legnth timees width
triagnlearea=1/2base times height
ok so we find volume of entier land first
we can cut into triangle an rectangle
triangle=height=650-200=450
base=600
area=1/2*600*450=135000 ft^2
rectangle=200 times 600=120000
add
135000+120000=255000ft^2
find other areas and subtract
areahouse=45*38=1710
areawooded=118*60=7080
frontyard=78*40=3120
add
1710+7080+3120=11910
minus
255000-11910=243090
how many acres are farmed
43560ft^2=1acre
divide both sides by 43560
1ft^2=1/43560 acre
multiply both sides by 243090
243090ft^2=243090/43560acre=5.5805acre=5.6acre rounded
answer is 5.6 acer
we have

we know that
<u>The Rational Root Theorem</u> states that when a root 'x' is written as a fraction in lowest terms

p is an integer factor of the constant term, and q is an integer factor of the coefficient of the first monomial.
So
in this problem
the constant term is equal to 
and the first monomial is equal to
-----> coefficient is 
So
possible values of p are 
possible values of q are 
therefore
<u>the answer is</u>
The all potential rational roots of f(x) are
(+/-)
,(+/-)
,(+/-)
