Question 1165345
<font face="Times New Roman" size="+2">


I convert everything to cents so that the mess of decimals are eliminated.  Dimes are 10 cents, quarters are 25 cents, and $6.30 is 630 cents. Let *[tex \Large x] represent the number of dimes.


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 10x\ +\ 25(2x\,-\,6)\ =\ 630]


Solve for *[tex \Large x] and then calculate *[tex \Large 2x\,-\,6]

*[tex \LARGE e^{i\pi}\ +\ 1\ =\ 0]
My calculator said it, I believe it, that settles it
