Question 227111
<font face="Garamond" size="+2">

Let *[tex \Large x] represent the number of dimes.  Then *[tex \Large 5x] represents the number of nickels.  Since each dime is worth $0.10, the value of all of the dimes is *[tex \Large 0.10x]. Likewise, since nickels are worth$0.05, the value of all of the nickels is *[tex \Large 0.05(5x)].  These two values total to \$42.35, so:

*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 0.10x\ +\ 0.05(5x)\ =\ 42.35]

Solve for *[tex \Large x] to get the number of dimes.  Multiply by 5 to get the number of nickels.
