Answer:
I can't understand your question. what is the meaning of these 3, 4 ,16 in your question
I think the answer would be 1/2
2t + 8 ≥ -4t - 4
2t+4t ≥ -8-4
6t ≥-12
t ≥ -12/6
t ≥ -2
where is the figure? I can't see it
Tax = 7 1/4% = 29/4
After tax, it would be, 89.79 + 89.79*29/4*100 = 89.79 + 2589.41/400
= 89.79+6.47 = $96.26
