13. 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.

Answer

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%)
