Lord and taylor hired 400 store santa's. if each santa sees 125 children a day for 30 days, how many children are seen by lord and taylor's santas?

Hello there, my fellow human being!
So, let's use the important information that was put in this word problem:
400 store santas were hired.
Each santa sees 125 children a day.
This continues for 30 days.

We can now figure this out.
400 * 125 = 50,000 children a day seen by all the santas
50,000 * 30 = 1,500,000 children seen by all the santas in 30 days total.

So, 1,500,000 children are seen by Lord and Taylor's santas.

Hope this helped!
