A manufacturing firm uses two measures of productivity:

Total sales$/$Total inputs

Total sales$/$Total labor inputs

Given the data for the last three years below, calculate the productivity ratios. All figures are in dollars. Round your answers to four decimal places.

Year $1$ Year $2$ Year $3$

Sales $$110$ $$129$ $$124$

Materials $627371$

Labor $283328$

Overhead $81210$

Year $1$ Year $2$ Year $3$

Total sales$/$Total inputs

Total sales$/$Total labor inputs

How would you interpret the results? Compare the results between two consecutive years.
