To answer this, you should convert both sides to an equal unit, like inches.
A yard is 36 inches, therefore the rope is 12 cents/36 per inch or 1/3 cents per inch.
The length of rope you are buying is 12 ft, 6 in or 144 + 6 or 150 inches.
Multiplying the length of rope in inches by the cost per inch: 150 * 1/3 = 50 cents.

Since you are buying in 'feet', change cost to 'feet' so you are on the same footing, so to speak. Therefore,
.12 a yard can be written as .12 / 1 yard
then (.12 / 1 yard) x (1 yard / 3 feet), the yards cancel each other and you are left with .04 cent per feet.
Since the cost is now per 'feet', you have to change 12 feet 6 inches to feet only, thus 12.5 feet, now
.04 / feet x 12.5 feet = 0.50 or 50 cents
