To determine the annual accretion, find the difference between the cost of the bond and par value; divide the result by the original number of years to maturity. The following question tests your understanding of accretion. Mr. Dancer purchases a 5-percent corporate bond with 10 years to maturity at 80.
Look for horsepower (HP) ratings to compare the lifting power between garage door opener models. Ratings ranging from 1/2-horsepower to 1-1/2 horsepower are typical for residential models. If you have a sectional double-car garage door, a 1/2-horsepower motor should be sufficient, but a higher-power model will operate with less effort and less wear and tear on the motor.
It is the cheapest of the three and least power. Â½ HP: This size opener is the most popular out of the three and is recommended for single or double garage doors with average weight (ex: carriage style door). Again, this opener will only be efficient when the door is properly balanced and an opener with more horsepower will last longer.
