Answer:
$151.8
Step-by-step explanation:
126.5 + (126.5*20%)
the original cost plus the cost times the tip
S=50x-x^2
dS/dx=50-2x
d2S/dx2=-2
Since acceleration is a constant negative, when velocity equals zero, it is at the absolute maximum point for S(x)...
dS/dx=0 only when 50-2x=0, 2x=50, x=25
So the price that will maximize income is $25.00 a seat.
And that maximum income is:
S(25)=50x-x^2
S(25)=$625.00
Answer:
20 2/3 feet
Step-by-step explanation:
7 3/4 * 2 2/3 = 20 2/3
Convert into improper fraction..
= 31/4 * 8/3
...
Solve equation...
= 20 2/3
The area of the garden is 20 2/3.

Answer:
2
Step-by-step explanation:
|x| means absolute value
|x| means if x is positive or negative, its still positive
-5|x|+4=14
-5|x|=10
|x|= -2
answer is 2
