Lee and fred are elementary school teachers. fred works for a charter school in pacific palisades, california, where class size reduction is a goal for 2013. lee works for a noncharter school where funds do not allow for class size reduction policies. lee’s fifth-grade class has 1.4 times as many students as fred’s. if there are a total of 60 students, how many students does fred’s class have? how many students does lee’s class have?

Fred’s class has 25 students.

Lee’s class has 35 students.

Step-by-step explanation:

You know that Lee’s fifth-grade class has 1.4 times as many students as Fred’s, then you can write the following expression:

Where L is the number of students that Lee’s class has and F  is the number of students that Fred’s class has.

You know that there are a total of 60 students, then you can write the following expression:

Substitute into the second equation and solve for F:

Then, L is:

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0
