Question

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?

Answer 1

No because 35×2=70. 70+35=105. 105% is above 100

Answer 2

Answer:

About 50% is the right estimation.

Step-by-step explanation:

She is wrong, because 35% doesn't fit with the amount of inbox and junk mail.

If she gets about twice as much regular mail as junk mail, then the right percentage would be 50%, that is, her junk mail is about 50% of regular mail. In other words, if her regular mail is twice than her junk mail, so her junk mail is about half her regular mail. It's just seeing the same problem, but from an opposite point of view.
