Price per pound = $25.52 / 14.5 = $1.76 per pound
I know the price of the beans cannot be $2.00 per pound because that would give me an answer of $29.00, which is too high.
I know the price of the beans cannot be $1.00 per pound because that would give me an answer of $14.50, which is too low.
Therefore I have bracketed the cost per pound between $1.00 and $2.00. I could have used other values for the bracketing values, but the checking is easy with the two values I picked.
