It might be 31 if you add all the numbers together but I'm not positive.
Divide 141 by 2, getting 70.5. Since 70.5 is halfway between two consecutive integers, 70 and 71, these are the locker numbers. (P.S. This method only works with odd numbers.) 70+71=141.
The discount would be $4.32, and the total after the discount would be $19.68.
With what subject? what question?
72/6+ 85/6
= (72+ 85)/6
= 157/6
= (156+1)/ 6
= 156/6+ 1/6
= 26+ 1/6
= 26 1/6
The final answer is 26 1/6~
