All basketballs at a sporting goods store were marked down 25% during the first week of a sale. During the third week, all remaining basketballs were marked down an additional 30%. If a basketball was originally $22, how much does it cost during the third week?

selling price= $9.9

Step-by-step explanation:

Giving the following information:

During the third week, all remaining basketballs were marked down an additional 30%.

Original price= $22

To calculate the selling price in the third week, we need to use the following formula:

selling price= original price*(1 - markdown)

selling price= 22*(0.45)

selling price= $9.9

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
