Money

Chen checked his wallet to see how much money he had. He counted n quarters, 8 fewer dimes than quarters, and 3 times as many nickels as quarters.

  • Write an expression that represents the amount of money Chen has.
  • Explain what each term in the expression represents.
  • Evaluate the expression for n = 10.

Hint:

  • Write an expression that represents the number of dimes. If there are 8 fewer dimes than quarters, that means there are n-8 dimes.
  • Write an expression that represents the number of nickels.
  • Then, since you want to represent the total amount, add the expressions together.
