Final answer:
To determine how many cards Zachary sold for Mother's Day, calculate 2% of 550 by multiplying 550 by 0.02. Zachary sold 11 cards for Mother's Day.
Step-by-step explanation:
The question asks how many cards Zachary sold if he was responsible for selling 2% of the 550 cards available for Mother's Day at Bob's gift shop. To find the number of cards Zachary sold, we need to calculate 2% of 550. The calculation is as follows:
Number of cards sold by Zachary = 2% of 550
To calculate 2% of a number, you can multiply the number by 0.02 (since 2% is the same as 2/100 or 0.02):
Number of cards sold by Zachary = 550 × 0.02
= 11 cards
Therefore, Zachary sold 11 cards for Mother's Day.
