Bob's Gift Shop sold 800 cards for Mother's Day. One salesman, Luis, sold 20% of the cards sold for Mother's Day. How many cards did Luis sell?

Answer 1

To find out how many cards Luis sold, we need to calculate 20% of the total number of cards sold, which is 800.

We can calculate 20% by using the formula:

\[ \text{Number of cards Luis sold} = \frac{20}{100} \times 800 \]

Calculating this gives:

\[ \text{Number of cards Luis sold} = 0.20 \times 800 = 160 \]

Thus, Luis sold 160 cards.
