The cost of a new york yankees baseball cap is $24.00. the local sporting goods store sells it for $30.00. find the markup rate.

The markup rate is 25%.

$30.00 -  $24.00  =  $6.00

24 x 25%

24  x .25 = 6

Hope this helps. :)

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
