Question

Can someone tell me how to do this?? i suck at word problems. Real-life absolute value inequalities.
Write an absolute value inequality for the following: Between 60% and 80% of Americans stink at writing absolute value inequalities. (Hint: Think of this as a margin of error problem.)

Answer 1

Number of Americans = A
Number of Americans that stink at solving these problems = S
S >= 0.6A and <= 0.8A

Therefore

0.6A <= S <= 0.8A
