Launch This Resource. In 1950, Erwin Chargaff published a paper stating that in the DNA of any given species, the ratio of adenine to thymine is equal, as is the ratio of cytosine to guanine. This became known as Chargaff's ratio, and it was an important clue for solving the structure of DNA. Downloads. Downloads.
The average annual overhead for a dental office (not including the dentistâs salary) is $350,000. The average clinician works 33 hours per week for 48 weeks, which is 1,600 hours per year. By taking the $525,000 average annual revenue and dividing it by 1,600 hours, we get $312 an hour to keep the office operating profitably.
For example, if the annual budget is based on a production quantity of 10,000 units and the direct labor required for each unit is three hours, the total direct labor is 10,000 x 3 or 30,000 hours. The total overhead expenditure is then divided by the total labor hours to arrive at the overhead rate.If, in the example, total overhead amounts to $120,000 a year, the overhead rate will be $120,000 divided by 30,000 hours, or $4 per hour.As each unit requires three hours of labor, the indirect cost of each unit is $4 x 3, or $12.or example, if the annual budget is based on a production quantity of 10,000 units and the direct labor required for each unit is three hours, the total direct labor is 10,000 x 3 or 30,000 hours. The total overhead expenditure is then divided by the total labor hours to arrive at the overhead rate.
