Duh!
If you can get to 7.50 then 25 (25 cents) goes into 75 3 times add the zero to get 30 quarters.
That’s what I got, too.
There are many who don’t understand “inverse” or its use in mathematics. That’s not uncommon. No use getting frustrated by it...
Beautiful, no? My friends in engineering school always wondered how I could integrate the most complex sinusoids without knowing any identities. Euler was the man who proved God existed, and will forever be crown prince of awesome.
“If a Euro is worth $1.50, five Euros is worth what?”
Her choices are A.) 30 quarters, B.) 50 dimes, C.) 70 nickels, and D.) 90 pennies.

Ummm ... lessee ...
1 Euro = $1.50 ... 5 Euros = $1.50 x 5 = $7.50 ...
90 pennies = 90 cents ... ummmm NO ...
70 nickels = 70 x .05 = $3.50 ... ummmm NO ...
50 dimes = 50 x .10 = $5.00 ... ummmm NO ...
30 quarters = 30 x .25 = $7.50 = the price of the 1017 page healthcare bill we can use if we run out of toilet paper ... CORRECTOMUNDO !!!
I have a PhD in engineering. I can do calculus, differential equations, linear algebra, statistics and design of experiments.
But I have ALWAYS had trouble with arithmetic.
Go figure :)
Doing it the long way is tricky. Doing it the short way is easy. You know 5 Euros is worth at least 5 dollars. Obviously, it’s not D. Everyone knows 90 pennies is less than even one dollar. It can’t be C either because...process of elimination.
She got caught up in the minor details.
I’m surprised she didn’t pick:
E) all the above
I was in Wal Mart a few years ago right around this time of the year. A girl and her mother were shopping for her back—to-school supplies, and it was obvious from the conversation that the girl had spent at least one year away at college. Daughter was charged with keeping tabs on their spending and had a calculator for said job. They had just put something in the cart, and there was a little complaining from the daughter. Mom said, “Well, it was 4 of them, so just put in 4 times 7.” The daughter proclaimed, without so much as lowering her voice, that she could not do this, explaining that she was out of school for the summer.
Now, I am a math moron and I am embarrased by my lack of skills. but, next to this girl, I felt like Einstein.
Seventy nickels being $3.50....
Sigh...
I cannot do math in my head after lunch.
oh, i agree- in enough time I did it a different way- 10 quarters is $2.50, times 3 = $7.50
But the others were so obviously wrong, process of elimination was the easiest way
Making her look stupid must have been set up by the liberals- she is a staunch conservative.
That one has me stumped too! It seems some people are good with numbers, while others are good with words. And a few are good with both.

I know what you mean. Sometimes I will give a cashier $23.53, for a 18.38 purchase, (don’t have the right change and don’t want dollars and pennies back) and it confuses the heck out of many of them.
If possible, I go further and give them $25.63 and avoid those dimes and nickles also.
Next time do this math equation in your head:
Irritating my wife for an hour = ________?
Your marraige mathematics needs some work.
I am *so* relieved to hear you say that. Math nut here, have that intuitive sense for probability and everything, bomb arithmetic regularly, was a mess the first month of game theory.
