Which of the following is a correct way to measure productivity? a. Divide the number of hours worked by the quantity of output.
b. Divide the quantity of output by the number of hours worked. c. Determine how much output is produced in a given time. d. Determine how much time it takes to produce a unit of output.
the easier way is to think 1 times any number is the same number so 380(1+0.18)=448.4 (just like adding tax to the price of something to see how much you'll actually pay)
