Answer:
-3.5??
Step-by-step explanation:
Work backwards :)
We are given
length of rectangular yard is x
so, ![L=x](https://tex.z-dn.net/?f=L%3Dx)
width of rectangular yard is
so, ![W=2x^2-98x+5](https://tex.z-dn.net/?f=W%3D2x%5E2-98x%2B5)
We are given
the length of the enclosed yard is 50 feet
so, we get
![L=x=50](https://tex.z-dn.net/?f=L%3Dx%3D50)
now, we can plug x=50 and then we can find width
![W=2(50)^2-98(50)+5](https://tex.z-dn.net/?f=W%3D2%2850%29%5E2-98%2850%29%2B5)
![W=105](https://tex.z-dn.net/?f=W%3D105)
now, we can find total fencing length
so, total fencing length is
![=2L+2W](https://tex.z-dn.net/?f=%3D2L%2B2W)
now, we can plug values
![=2\times 50+2\times 105](https://tex.z-dn.net/?f=%3D2%5Ctimes%2050%2B2%5Ctimes%20105)
![=310feet](https://tex.z-dn.net/?f=%3D310feet)
now, we are given
the cost of fencing is $13 per foot
so,
total cost = (cost of fencing)*(total fencing length)
we can plug values
![C=13\times 310](https://tex.z-dn.net/?f=C%3D13%5Ctimes%20310)
![C=4030](https://tex.z-dn.net/?f=C%3D4030)
So, Janice will spend $4030.........Answer
If you apply the or both
Only 1 of the students would need to know the "or both", therefore maximizing the remaining amount of students you can put in.
Gerald, let's call him, knows French AND German, so there's only one less student that knows french and german. Gerald is 1 student.
MAXIMUM:
There are now 14 monolinguistic French speakers and 16 monolinguistic German's, 30 students + Gerald=31.
Minimum:
As a bonus, the minimum is 15 students knowing french AND German and only 2 monolinguistic German speakers, so 17.
