Question

Anita has 180 minutes to prepare mailers for her job. It takes her at least 15 minutes to set up materials and 3 minutes per mailer to prepare them. If m represents the number of mailers she prepares, then 3m + 15 ≤ 180 represents the number she can finish. What is the greatest number of mailers Anita can prepare in the time she has?

Answer 1

Solve the equation.

\(3m + 15 \le 180\)

Subtract 15 to both sides, what's 180 - 15?

Answer 2

*inequality

Answer 3

165

Answer 4

Yes, now we have:

\(3m \le 165\)

Now divide 3 to both sides.

Answer 5

165 / 3 = ?

Answer 6

55

Answer 7

Yes, so we have:

\(m \le 55\)

So the greatest number of mailers Anita can have is 55.
