**Ms. Sue**, Sunday, July 10, 2011 at 8:02pmWhich part of this do you not understand?

Let x = the number of students who do not work full time.

x + 7x = 11,600

8x = 11,600

x = 1,450

**Reiny**, Sunday, July 10, 2011 at 8:24pmTry this:

Let the number of students who do not work be x

then the number of students who work = 11600-x

You said:

"There are seven times as many students who work full time as there are students who do not"

or

The number of students who work is 7 times the number of students who don't work ----> 11600 - x = 7x

or 7x + x = 11600

which is the equation that Ms Sue gave you
