Final answer:
To find the total number of cards sold for Mother's Day, we set up an equation using the information given. By solving the equation, we determine that a total of 220 cards were sold for Mother's Day.
Step-by-step explanation:
To find the total number of cards sold for Mother's Day, we need to use the information given. We know that one salesman sold 22 cards, which was 10% of the total number of cards sold.
Let's assume the total number of cards sold for Mother's Day is X. Since the 22 cards sold by one salesman represent 10% of the total, we can set up the equation:
0.10 * X = 22
To solve for X, we divide both sides of the equation by 0.10:
X = 22 / 0.10
X = 220
Therefore, a total of 220 cards were sold for Mother's Day.
