Question

The number of freshman at George Washington high school is 60 greater than the number of sophomores. If there are 1250 students total and both grade levels, how many freshmen are there? Which type of system does this represent?

A:relative

B:break-even

C:total-value

D:perimeter

Answer 1

Hence total number freshman presented are 655.

The system is relative system as there is correlation between freshman and

sophomores.( as freshman are 60 more than the Sophomores)

Explanation:

Given:

1250 total students of sophomores and freshman.

To Find:

freshman count and its type of system used.

Solution:

We have that ,

consider x be the no.of freshman and y be the sophomores

So by given condition,

x+y=1250 ,..............................Equation(1)

And other one,

x=60+y

Use above value in equation (1) we get ,

60+y+y=1250

2y=1250-60

y=595

Now number of freshman ,

x+y=1250

x=1250-595

x=655

Hence total number freshman presented are 655.

The system represent the relative proportion system.The break even and total value should include all students in university .

Relative means in relationship with one another .

As there are 60 more number of freshman than the sophomores.
