Question 247790
<font face="Garamond" size="+2">

Let *[tex \Large q] represent the number of quarters.  Let *[tex \Large h] represent the number of half-dollars.  Then *[tex \Large 25q] is the value of the quarters in cents and *[tex \Large 50h] is the value of the half-dollars in cents.  The total amount of money he has, expressed in cents, is 425.


He has 14 coins:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ q\ +\ h\ = 14]


The total value is $4.25:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 25q\ +\ 50h\ = 425]


Either of the elimination or substitution will work just fine to solve this system, but given the simplicity of the first equation, I would choose the substitution method.


Let me know what you obtained for an answer.
