First, put each grade in terms of x. Most grades are compared to Sophomores, so I made that x
Freshmen = x + 10
Sophomores = x
Juniors = x + 20
Seniors = (x + 10) + 7 = x + 17
Then, the total number of students = 363, so we’ll make an equation that adds them all up in terms of x to equal 363
(x + 10) + x + (x + 20) + (x + 17) = 363
Combine like terms:
4x + 47 = 363
Subtract 47 from both sides:
4x = 316
Divide both sides by 4:
x = 79
The question was how many seniors there are. Seniors were x + 17, so 79 + 17 = 96
Answer:
Total area of field sold(35*35)+(51*25)=2500
Area of square field is 2500
One side = 
= 50
So, the perimeter of the square(4*a)=4*50=200
Cost of fencing = 200*1.5 usd = $300
Step-by-step explanation:
1(x)+3=total cost
x=the number of rides you go on
