Adding 7.9 percent to 20 dollars gives 20 x (1 + (7.9/100)) = 20 x 1.079 = $21.58
79 + (3%) = 81.37
15.8

If the tax is 8 percent, multiply 79 by 1.08
$55.30 (I presume you want to know how much is left when you subtract 30% of $79 from $79. 30% of $79 is $79 times 0.3 which is $23.70. Subtracting this from $79 leaves $55.30.)
79 percent out of 100 percent is 79% or 0.79.
This cannot be correctly answered without knowing the tax rate.
79.
