The total number of sandwiches made is 100% of the sandwiches.
If 40% of the sandwiches are cheese sandwiches, then since 100% - 40% = 60%, 60% of the sandwiches are chicken sandwiches. We are told that there were 288 chicken sandwiches,
Now you need to solve this problem.
60% of what number is 288?
Translate it into an equation.
60% * x = 288
0.6x = 288
Divide both sides by 0.6
x = 288/0.6
x = 480
Answer: 480 sandwiches were made.
