Sam has proudly said that his management effort has led to increase in sales. However,

John remembered that as in August 2019 all the selling prices were increased by 6%. At the same time, all salaries were increased by 8% to increase attractiveness to new employees and to keep present employees from leaving.

John is asking you to help analysing the performance by evaluating sales variances%, F&B costs% and labour costs% with known information in comparison to the previous years results and explain the results to him. Help him do this.
