At a ski shop, Marvin saw a snowboard on sale with a regular cost of \$24.75. The snowboard is now on sale at a 12% discount. Approximate the amount of the discount.

What is the discount amount?

Regular \$24.75

12% off

Approximate

To find the amount of discount, I multiplied the cost of the snowboard by the discount percent (converted to a decimal). Since it said to approximate, I rounded the \$24.75 to \$25.

The discount amount is \$3.00.
