Q. Bob's Gift Shop sold 200200 cards for Mother's Day. One salesman, Jacob, sold 10% 10 \% of the cards sold for Mother's Day. How many cards did Jacob sell?\newlineAnswer:
  1. Calculate 1010% of Total Cards: To find out how many cards Jacob sold, we need to calculate 10%10\% of the total cards sold for Mother's Day. Since the total number of cards sold is 200200, we need to find 10%10\% of 200200.\newlineCalculation: 10%10\% of 200=(10100)×200200 = (\frac{10}{100}) \times 200
  2. Perform Multiplication: Now we perform the multiplication to find the number of cards Jacob sold.\newlineCalculation: (10100)×200=0.10×200=20(\frac{10}{100}) \times 200 = 0.10 \times 200 = 20
  3. Final Answer and Checking: We have calculated that Jacob sold 2020 cards. This is the final answer, and we should check it to ensure there are no mathematical errors.\newlineChecking: 10%10\% of 200200 is indeed 2020, which means the calculation is correct.
