A suitable probability calculator will show that probability to be .135905122.
_____
Your class extends from 1 standard deviation above the mean to 2 standard deviations above the mean. The empirical rule puts that probability at ...
... (1/2)(95% - 68%) ≈ 13.5%
The empirical rule tells you 68% of observations lie within 1 standard deviation of the mean, and 95% lie within 2 standard deviations. Then the number that lie between 1 and 2 standard deviations from the mean will be the difference of these values. You want the values in the region above the mean only, so you only want half the difference just described.
First let's convert 7.5% into a decimal by doing Beyoncé on it and move the decimal two places to the left.
Now let's multiply the cost of the DVD by the converted percent,
Now let's add the above number to the original price, remember, $2 is not exact.
