Answer:
D. 32 ft^2
Step-by-step explanation:
You find the mean of the two bases 7+9= 16 16/2=8 Then multiply 8 by 4 to get 32 ft ^2
Let, the number of students = x
Number of teachers = y = 6
Equation would be: 6x + 8.5y = 250
6x + 8.5(6) = 250
6x + 51 = 250
6x = 250 - 51
x = 199 / 6
x = 33.16
Students can't be in fraction, so after rounding-off, it will be 33
In short, Your Answer would be 33 Students
Hope this helps!
