This question has three parts.
At the grand opening of a store, the owner gave away stickers and T-shirts to some of the customers.
• A total of 180 customers visited the store at the grand opening.
• Every 10th customer received a free sticker.
Every 25th customer received a free T-shirt.
Part A
What is the total number of customers who received a free sticker? Show or explain how you got your answer.
Part B
What is the total number of customers who received a free T-shirt? Show or explain how you got your answer.
Part A:
To find the total number of customers who received a free sticker, we need to determine how many customers out of the 180 received a sticker.
Every 10th customer receives a free sticker, so we will divide the total number of customers (180) by 10.
180 ÷ 10 = 18
Therefore, a total of 18 customers received a free sticker.
Part B:
To find the total number of customers who received a free T-shirt, we need to determine how many customers out of the 180 received a T-shirt.
Every 25th customer receives a free T-shirt, so we will divide the total number of customers (180) by 25.
180 ÷ 25 = 7 remainder 5
Since the remainder is 5, this means that 5 additional customers received a T-shirt on top of the 7 who received it exactly on the 25th visit.
Therefore, a total of 7 + 5 = 12 customers received a free T-shirt.
