The semester project came back from the copy store and the project leader has just noticed that the left side y-axis of a key Pareto chart was cut off due to a printing error. The bar chart component uses the missing left side y-axis and the cumulative percentage line on the Pareto chart uses the right side y-axis. The project leader is pretty sure that the total number of observations in all combined categories is 200. Can you help him develop estimates of the counts for each of the five categories in the figure below?

Show your calculations and you may use approximations wherever you feel necessary.
