A manager checked production records for the week and found that a worker produced 94 units of output in 32 hours. In the prior week, the same worker produced 89 units in 39 hours. What is the percentage change in productivity for this worker? (enter in decimal format without a percent sign, e.g. 50% should be entered as .5) I suggest you use excel for homework assignments. You will be able to see exactly what calculations you did, which will help in finding any mistakes. Also, any subsequent attempts will go faster because your formulas will already be entered -- you'll just need to update the numbers. You can cut and paste your answers into canvas, which will automatically round your answer to four decimal places. If you are doing the calculations by hand, use at least six decimal places to avoid rounding errors
