my ans isnt matching any of the choices. the ans in the solu is E. please explain if u can solve this.


Given:
\(h+c=3.59\), \(h+f=4.4\) and \(f=2c\). Q: \(f=?\)

Subtract 1 from 2: \(h+f-h-c=4.4-3.59\) --> \(f-c=0.81\), as \(f=2c\), then \(f-\frac{f}{2}=0.81\) --> \(f=1.62\).

Not a good question.

This problem was posted in 2,003 and it has been removed. It was wrong. I think that the problem is in the cost $3.59. It should be $3.95.
That way the problem would be correct.
