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.
The horsepower needed for your garage door opener is dependent on whether or not you want a long lasting opener verses replacing it every few cycles, or the size of the door. For example, if you would like to lift a double garage door, one might suggest using a 1/2 horsepower because the door is heavier and larger.
