29.99 - 10% of 29.99
29.99 - 0.10(29.99) = 26.99

or

if it is 10% off, then u are paying 90%
90% of 29.99
0.9(29.99) = 26.99
in order to figure this out we need to change 10% into a decimal. 
10% = 0.10 
Now we multiply 0.10 x 29.99 = 2.999 
Since it asks "off of" 
meaning to take away 10% from 29.99
we have to subtract 
sooooo...
29.99 - 2.999 = 26.991

So your answer is 26.991

Good Luck!
