if the value on the right hand side of the equations is 415, the problem is being done in cents.  A dime = 10 cents.  We know there are 4 dimes.  We need an equation that has 4*10 or 40 on the left hand side.  A quarter is worth 25 cents, and it appears $x$ is the number of quarters.  The value of $x$ quarters (in cents) will be $25x$.  

value of dimes = 4*10 = 40
value of quarters = 25x

value of dimes and quarters in jar = 415

which equation will represent that?
