A. By reducing the cost of a haircut by using inexpensive hair
products
B. By placing ads in the newspaper to attract new customers
O
C. By checking with the government to determine how much tax to
charge the customers
D. By subtracting all the costs from the amount of money the
customers paid

The answer is (D) By subtracting all the costs from the amount of money the customers paid.

Explanation:

When we get the total costs and the amount customers paid we just need to subtract to get the profit made that month.

(m being total amount of money, c being the costs and p being the profit)

m - c = p

think of it this way, if we have an empty bag and each person that comes by puts one candy on the bag and 10 people come by we get a total of 10 candies, then we eat 5 candies to satisfy our desire for candy then we are left with 5 candies.

(the 10 people being customers, the 5 candies being the costs and the leftover 5 candies being the profit)
