The answer to the question is A. What you do, is first get rid of the fraction by multiplying everything by 5. You should then have
1004x>=80. Now subtract 100 from each side. Then what your going to want to do is divide each side by 4. Don’t forget that when you divide by a negative number and there is greater than or less than sign, the sign automatically changes the opposite way.
204/5 x>=16
5(204/5 x)>=(16)5
1004x>=80
4x>=20
x<=5
A.

20 – 4/5x >= 16
4/5x >= 4
4/5x <= 4
4x <= 20
x <= 5
Therefore answer is A.
