If 20% was taken off, that means that 35.96 is 80% of the original price.
35.96 =

Now, we just need to put it into fractions, cross multiply, and divide to find the original price.

35.96×100 = 3596
1×80 = 80
3596÷80 = 44.95
Now, to make sure, we multiply 44.95 by 20%,
44.95×0.20 = 8.99
Subtract that from 44.95
44.95-8.99 = 35.96
That is the sale price of the alarm clock.
This means that yes, the regular price of the mp3 alarm clock was
$44.95
