Benny has 64 coins in his pocket.  Let's say that $x$ of them are pennies, worth 1 cent each.  Then $64-x$ of them are quarters, worth 25 cents each.

If the total value is $4.00 * 100 cents/$1 = 400 cents, then the value of the quarters plus the value of the pennies must add up to 400 cents.

$x$ pennies are worth $1x$ cents.  
$(64-x) $ quarters are worth $25(64-x)$ cents.

Can you write and solve an equation using those two expressions that shows the value of the pennies and quarters equalling 400 cents?
