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
