Here are the steps to solve these menu planning and cost control problems:
1) Given the following information, calculate cost percentages:
a) Cost $200, Sales $500 = Cost/Sales x 100 = 40.0%
b) Cost $150, Sales $500 = 30.0%
c) Cost $178.50, Sales $700 = 25.5%
d) Cost $216.80, Sales $800 = 27.1%
2) Calculate cost percentages:
a) 28.0% of $500 is 0.28 x $500 = $140
b) 34.5% of $2,400 is 0.345 x $2,400 =
