I will try my best to assist you with your question ,
First we must divide the amount by 2
334/2 = 167
Now we add 16
167 + 16=183
So, the girl spent $183
Wow, she is spoiled!
Hope I helped!
Good Luck!
I am pretty sure it is 120 or 30
0 + -4 = -4
the 0 has no value and cannot add anything on top of the -4
So -4 stays the same:)
Answer = -4
Good Luck! :)
