Question 623754
<font face="Times New Roman" size="+2">


Let *[tex \LARGE x] represent the number of dimes.  Then *[tex \LARGE 35\ -\ x] must represent the number of nickels, *[tex \LARGE 10x] is the value of the dimes in cents, and *[tex \LARGE 5(35\ -\ x)] is the value of the nickels in cents.  Since we have expressed the value of the individual types of coins in cents, let's express the total value of the coins in cents:  $3.30 = 330 cents.


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 10x\ +\ 5(35\ -\ x)\ =\ 330]


Solve for *[tex \LARGE x], then calculate *[tex \LARGE 35\ -\ x]

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