Answer:
We can use the concept of percentage to solve this problem.
Let's represent the total number of cards sold for Mother's Day by "x". We know that one salesman sold 47 cards, which was 4% of the total number of cards sold. So we can set up an equation:
0.04x = 47
Solving for "x", we divide both sides by 0.04:
x = 47 / 0.04
Using a calculator, we get:
x = 1175
Therefore, the total number of cards sold for Mother's Day was 1175.
