Question

An elementary school consists of kindergarten (grade 0) through grade 5. The equation n = -389 + 378 can be used to determine the number of students, n, who started the school in kindergarten and who are still in the school at grade g. Which description represents the meaning of 378?

Answer 1

A. The number of students who started school in kindergarten.

Step-by-step explanation:

The equation that represents the number of students who started school in kindergarten and who are still in the school at grade g is:

n = -38g + 378

So, 378 is the number of students when g is equal to 0 because

If = 0, we get:

n = -38g + 378

n = -38(0) + 378

n = 0 + 378

n = 378

Therefore, 378 means the number of students who started school in kindergarten.
