The value for m is -5
Putting the x⁵ on the denominator is just a way to get rid of the negative exponent.
1.
If no changes are made, the school has a revenue of :
625*400$/student=250,000$
2.
Assume that the school decides to reduce n*20$.
This means that there will be an increase of 50n students.
Thus there are 625 + 50n students, each paying 400-20n dollars.
The revenue is:
(625 + 50n)*(400-20n)=12.5(50+n)*20(20-n)=250(n+50)(20-n)
3.
check the options that we have,
a fee of $380 means that n=1, thus
250(n+50)(20-n)=250(1+50)(20-1)=242,250 ($)
a fee of $320 means that n=4, thus
250(n+50)(20-n)=250(4+50)(20-4)=216,000 ($)
the other options cannot be considered since neither 400-275, nor 400-325 are multiples of 20.
Conclusion, neither of the possible choices should be applied, since they will reduce the revenue.

Answer:
Area: 28 cm^2 Perimeter=20 cm
Step-by-step explanation:
A= 1/2 x b x h
A= 1/2 x 8 x 7
A= 28cm^2
P=a + b + c
P = 6+8+6
P = 20 cm
