Re: Things Mom never told us about NSA Which reminds me....Here’s a simple arithmetic question: A bat and ball cost a dollar and ten cents. The bat costs a dollar more than the ball. How much does the ball cost?

I knew as soon as I answered I was wrong, but couldn't express how I knew, and totally forgot how to frame the question algebraically. I kind of slid into the correction sideways: If the ball costs 10 cents, then the dollar for the bat is only 90 cents more ...
But I got the lake answer right!
quote:
In a lake, there is a patch of lily pads. Every day, the patch doubles in size. If it takes 48 days for the patch to cover the entire lake, how long would it take for the patch to cover half of the lake?
For some reason I did not fall into the shortcut trap (... to divide the final answer by half. That leads you to twenty-four days.)
I don't know why the answer to this one seemed so obvious, having failed the other. Maybe a vague recollection of geometric progression? Or was that exponential growth? Anyway, I figured it out by avoiding the mental trap.

Numbers are indeed fun. Very enjoyable video!!
A book I have enjoyed and can highly recommend is "Fermat's Last Theorem."
It provides a glimpse into advanced topics without having to fully understand them. |

Ah, 9th grade algebra. Nun slapping me on the back of my head for sleeping. But I remembered the word problems.
X is the price in cents of the ball.
X+100 is the price in cents of the bat.
X+(X+100)=110
2X+100=110
2X=10
X=5
X+100=105 |
