Solve one-step money word problems

A learner interprets one-step situations involving prices, amounts paid, totals, and differences, represents dollar-and-cent quantities in decimal notation, and determines whether addition or subtraction models the relationship, including finding a cost, total, or change. The learner aligns dollars and cents, explains the meaning of the answer in context, and understands that a decimal point separates whole dollars from cents; multi-step problems, rates, and more advanced decimal operations are not included.

Detailed Explanation: Solve one-step money word problems

A money word problem tells you about a price, an amount paid, a total, or a difference.

  • Use addition to find a total or combine amounts.
  • Use subtraction to find how much more, how much less, or the change.
  • Line up the decimal points. The digits to the left show dollars, and the digits to the right show cents.

Example:
A notebook costs 6.75.Youpaywith6.75. You pay with 10.00. How much change should you get?

  1. Decide what the problem asks. It asks for the change, so subtract the price from the amount paid:
10.00−6.7510.00-6.75
  1. Line up the decimal points:

      10.00
    -  6.75
    --------
    
  2. Subtract:

10.00−6.75=3.2510.00-6.75=3.25
  1. Write the answer with a dollar sign:

    You should get $3.25 in change.

The answer makes sense because the change is the amount left after paying for the notebook.
