Question: A store is selling shirts for $181 each. If a customer buys 3 shirts every month for 2 years, how much money will they spend on shirts approximately?

To find the total amount spent, we can multiply the cost of a shirt by the number of shirts bought each month. So, $181 * 3 shirts = $543 spent per month. Since there are 12 months in a year, the annual expenditure on shirts is $543 * 12 = $6,516. Over 2 years, the customer will spend approximately 2 * $6,516 = $13,032 on shirts.

Math question: If the number 181 is multiplied by the product of its digits and then squared, what is the result?

To solve this, we first find the product of the digits of 181, which is 1 * 8 * 1 = 8. Next, we multiply 181 by 8, giving us 1448. Finally, we square 1448 to find the result. The square of 1448 is 2,096,704. Therefore, the final answer is 2,096,704.

Math Question: John has a collection of small stickers. If he gives away 181 stickers and then receives 3 stickers every day for one week, how many stickers will he have after the week?

Initially, John has 181 stickers. Over a week, he will receive 3 stickers per day, leading to a total of 3 * 7 = >21 stickers. Adding these stickers to his initial collection, he will have 181 + 21 = >202 stickers after the week.
