Question 985237

Let &nbsp;<B>q</B>&nbsp; be the number of quarters Johny has.


Then the number of dimes in his possession is &nbsp;2q. 


Thus you have an equation


25q + 10*2q = 675.


Solve it:


(25 + 20)q = 675,


45q = 675,


q = {{{675/45}}} = 15. 


So, &nbsp;Johny has &nbsp;15&nbsp; quarters and &nbsp;2*15 = 30 dimes. 


<B><U>Check</U></B>: &nbsp;15*25 c + 30*10 c = 675 c.
