Solution'
To find the groups profit:
The formula for profit = Total income - Total cost
Cost of the muffin sales = since it cost $3.50 to bake a muffin
1 dozen = 12 (3.50) = $42
For a youth group of 15
The total cost of sales = 15 x 42 = $630
profit = total income - total cost
Profit = $1035 - $630
Profit = $405
