Question

  1. critique reasoning marna thinks that about 35% of her mail is junk mail. she gets about twice as much regular mail as junk mail. is she correct? explain.

Explanation:

Step1: Let the percentage of junk mail be \(x\)

Let the percentage of junk mail be \(x\). Then the percentage of regular mail is \(2x\).

Step2: Use the fact that the sum of percentages is \(100\%\)

Since \(x + 2x=100\%\), we have \(3x = 100\%\), so \(x=\frac{100}{3}\%\approx33.3\%\)

Answer:

No, she is not correct. The percentage of junk mail is approximately \(33.3\%\) not \(35\%\)
