AND NOW, A BIT OF MATH.

And you still opened this post? Congratulations.

As a semi-retired math teacher, I see math in many everyday things. I rode an elevator the other day and wrote 3 pages of problems about the weight/capacity sign. (If it crossed your mind to send a sympathy card, did you plan to send it to me or to those who put up with me?)

Anyway, my question is this: After viewing the following cartoon, what is the probable age of the mom?

Depends on the age that one is no longer a kid. If 18, then the answer is 51.4.

Am I right, Teach?

She's 29, of course! (Or 39, depending on personal preference.)

If you're a kid at 21, then she's 60! (that's .35x=21). If 18, that's 51.4...
BS math '64, at 30.88% (hey, we couldn't drink before 21 so 21 it is)

Mainly, I wanted to see how this group interpreted the comic, and everyone passes.

If childhood ends at 21, she's 60. (0.35x = 21, or 35% of x = 21)

At 18, she's 51+ (0.35x = 18)

At 12, she's 34+ (0.35x = 12)

Since the child is probably about 11 (Inside knowledge - I follow this comic, so I know he's in 5th grade), I vote for 34. If she's 60 or 54, he was born pretty late (Her age being 40+ at birth), which, while possible, is a bit unusual. Plus, and this is the big factor, child discounts at theaters and parks, etc. end at age 12.

I plan to use this comic as a conversation starter when my GED students are working on percent.
Thanks
