When solving anproblem including money a negative answer can represent debt (how much you owe)
I can answer the first four
1 is 40%
2 is 60
3 is $1.35
4 is 6%
Inside the root is 50-1
50-1 = 49
You would remain with root 49 but, if you calculate the square root the answer would be 7 because...
7•7 = 49
^ So, the answer is 7
