Question 991258
<font face="Times New Roman" size="+2">


*[tex \Large  x] is the number of pennies and also the number of dimes.  *[tex \Large y] is the number of quarters.  The total number of coins is 35, so:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 2x\ +\ y\ =\ 35]


Pennies are worth 1 cent, dimes are worth 10 cents and quarters are worth 25 cents.  The total amount of money is 368 cents, so:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x\ +\ 10x\ +\ 25y\ =\ 368]


Solve the 2X2 system for *[tex \Large x] to find the number of pennies and the number of dimes, and *[tex \Large y] to find the number of quarters.
