The price of a skateboard, which normally sells for $50,, was decreased by 10% then decreased again by 10%, then increased by 10%. what was the overallchange in the price of the skateboard?

The price dropped by $5.45.

Step-by-step explanation:

    Initial price = $50.00

      Less 10 % =   -5.00

 1st sale price =   45.00

       Less 10% =    -4.50

2nd sale price =   40.50

      Plus 10 % =   +4.05

     Final price = $44.55

Change in price =   final   -  initial

                          =   44.55 - 50.00

                          = -$5.45

The price dropped by $5.45.

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
