Here's one:

How do you find the actual retail value of an even-money priced item that totals $30 cash when the sales tax rate is 12.5% ?

First of all, I'd find a way to buy online to avoid sales tax, or move to/buy at another locale with a lower tax rate.

Item retails for 'X'
At checkout, the tax is added at 12.5% of 'X'

Thus you are paying 1.125X, which is the stated $30. Equation would be:
1.125X = 30
or
X = 30/1.125 = $26.67 (actually $26.66666666...); but all depends on the tax charting for the range around $26.66 and $26.67

Oh, for crying out loud! How can you guys think so hard before it is even noon?

Very good, Beetle -- well done!

Hi Phyllis & Beetle

Well done Beetle -- you are most definitely quick !

We oversee a Mom & Pop motel in Volusia County Florida.

6.5% Sales Tax

+

6% Bed or Tourist Tax

Phyllis: It was the noon hour when I prepared my response. Time Zones are in effect during the holidays...

Burt: $30 for a motel room? Is that a per night cost or hourly?

Standing joke is No Refunds -- sometimes it takes less than $5-$15min. -- Yikes !

Early '80's was buck-wild... I must have a hell of an immune system !

I had a dream last night that me and Kris Krsitoferson were hitin' the bars and his 'ole lady showed up and we had some steak and beer -- a lot of shake it but don't dislocate it !!

I got to clean the bathrooms... 30+ years now -- you've seen my current pic -- Yikes

Cabbage Patch cole slaw is lame compared to pure 'ole mud wresilin' girl on girl on Main St.

Those were the days my friend...

Even the math problem enters into the mud puddle discussion...

An Eagle flying over an Indian by a River is a mnemonic for what radical mathematical equation that got a German Professor kicked out of academia and had to support himself by teaching piano lessons because his proposal was 100 years ahead of his time ?

Hint: We could not be having this conversation if that mathematical equation was not being in use right now.

Would that be Georg Ohm?
I'm seeing E=volts; R=resistance; & I=amperage and this can be placed into Ohm's Law Triangle having E over IR to easily present the equation permutations; i.e. E=IR; I=E/R; & R=E/I
