Peninsula Candy Company makes three types of candy bars: Chewy, Chunky, and Choco-Lite (Lite). Sales volume for the annual budget is determined by estimating the total market volume for candy bars and then applying the company's prior year market share, adjusted for planned changes due to company programs for the coming year. Volume is apportioned among the three bars based on the prior year's product mix, again adjusted for planned changes for the coming year.

The following are the company budget and the results of operations for July.
