(a)
Answer to Problem 34PPE
There two conversion factor
Explanation of Solution
Given information:
The given cost is 87 cents per day.
Calculation:
It is known that
Thus, convert 87 cents per day into dollar per year.
Thus, the cost is
Hence, there two conversion factor
(b)
To find: The process to choose the appropriate conversion factor.
(b)
Answer to Problem 34PPE
The process to choose the appropriate conversion factor is to check the units of the quantity.
Explanation of Solution
The process to choose the appropriate conversion factor is to check the units of the quantity.
Units determined that where to operate different measurements, since, only alike units can operates.
For example distance and time. There is no way to compare distance with time, since both are different units.
In this case dollar and cent both represent the same quantity and day and hour represent the same quantity.
Hence, the process to choose the appropriate conversion factor is to check the units of the quantity.
