Answer:
2.67 trays
Step-by-step explanation:
Calculation for how many trays must be sold to cover all costs including labor
First step is to calculate the Total Labor
Total labor = $7 per hour*8-hour shift
Total labor=56
Second step is to the profit per tray
Profit per tray=$35-$14
Profit per tray=$21
Now let calculate how many trays must be sold
Using this formula
Numbers of trays to be sold=Total labor/Profit per tray
Let plug in the formula
Numbers of trays to be sold=56/21
Numbers of trays to be sold=2.67 trays
Therefore the numbers of trays that must be sold to cover all costs including labor is 2.67 trays
