Take the original price, multiply it by 20% (you have to move the decimal place two to the left, so it becomes .2), then subtract the answer from the original price.
39.99*.2= $7.998
39.99-7.998= $31.99
If you wanted to, you could also round the $7.998 to $8.00. Your answer would be the same.
If a(2) = 0, then k=2. The product of the zeros is
(2)*(3)*(6)*(-3) = -108
The absolute value of the product of zeros of a(t) is 108.

Cos N= 5/13, and tan N=12/5.
