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.

Scientists would look for new evidence.

Step-by-step explanation:

Anytime scientists have different interpretations, they carry out more experments to look for new evidence. But this is after they must have tested their own hypothesis. If non of these are possible, they set out to get fresh evidences. Having different opinions would make them come up with new ideas with hope that their theories are valid. And it would also make them carry out more experiments for confirmation or for denial.
