There are 599 people on the tenth night and 4111 if you add all the nights together.
If I did 14 lawns in 7 hours, I would have done 2 yards every hour! Hope this helps!
Note that both 5 and 4 are exponents, and their product is 5*4=20, or 4*5=20. Thus,
(3^5)^4 is equal to (3^4)^5
Review:
(a to the power b)to the power c = a to the power bc.
Thus, (3 to the power 5)^4 = 3^20; the same is true if you reverse the positions of the 5 and the 4.
360 - 20 + 2x = 360
340 + 2x = 360
2x = 20
x = 10
