Question 1048618
<font face="Times New Roman" size="+2">


Let *[tex \Large x] represent the number of quarters.  Then *[tex \Large 18\ -\ x] must be the number of dimes.  There are *[tex \Large 25x] cents in *[tex \Large x] quarters.  There are *[tex \Large 10(18\ -\ x)] cents in *[tex \Large  x\ +\ 7] dimes.  $2.40 is 240 cents.


*[tex \LARGE \ \ \ \ \ \ \ \ \ \  25x\ +\ 10(18\ -\ x)\ =\ 240]


Solve for *[tex \Large x] then calculate *[tex \Large 18\ -\ x]

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