11) If rope costs $3.20 per yard, or $0.15 per inch, which is the better deal? 

NOTE: 1 yard equals 3 feet equals 36 inches

1. 15 cents per inch
2. $3.20 per yard
3. Both are the same.
4. Information provided is not enough to determine an answer.

Breaking down the word problem, you're essentially left with two operations: division and multiplication.

$3.20 for a yard is the same as stating $3.20 for 36 inches. Compare that answer to the multiplication of 15 cents times 1 yard (or 36 inches).

Under the latter operation (.15*36), your final answer is $5.40 -- much higher than $3.20 for the same length of rope.
