A Chinese restaurant uses about 15 exponent 2 appearance of chopsticks each day the manager wants to order a 30-day supply of chopsticks chopsticks come in boxes of 750. How many boxes should the manager order

9 boxes of chopsticks.

Step-by-step explanation:

The first thing is to calculate the number of chopsticks spent in a day, the problem tells us that they are 15 ^ 2 = 15 * 15 = 225 chopsticks daily.

To calculate the number of chopsticks in 30 days, it is to calculate the previous amount by 30:

225 * 30 = 6750 chopsticks spent in one month.

To know how many boxes you should order is to divide the total number of chopsticks in a month and the number of chopsticks that a box brings that are 750:

6750/750 = 9 boxes of chopsticks.

Therefore you should order exactly 9 boxes of chopsticks for the restaurant's need.
