Margaret [11]

The price after the discount was $45.

When the sporting goods store bought the snowboard and marked it up by 25%, the price became:

<em>= Original cost x ( 1 + markup percentage)</em>

= 120 x ( 1 + 25%)

= 120 x 1.25

= $150

The snowboard was then discounted by 70%, the new price becomes:

<em>= Current price x ( 1 - discount rate)</em>

= 150 x ( 1 - 70%)

= 150 x 30%

= $45

In conclusion, the price after the discount was $45.
