The answer is A. You have to isolate the variable(f) by subtracting 0.2 from both side. When youve done that, the answer should be -3.2
68% +75 % +79 % +x ÷4≥ 80%
.68 + .75 + .79+x ÷4* 4 ≥ . 80*4
.68 + .75 + .79+x ≥ 3.2
2.22 + x ≥ 3.2
2.22 -2.22+x ≥ 3.2 -2.22
x ≥ 0.98
She has to get at least 98% to get an B.
