There are 5 fewer dimes than nickels and 2 more quarters than dimes. If x equals the number of nickels, write an algebraic expression that represents the value of the pile in cents. Simplify the expression. [Hint: If x represents the number of nickels, then what do x – 5 and (x – 5) + 2 represent?] </SPAN>\n" );
