There are two ways you can figure this out.
1: 7.95-3.2-1.05= 3.7
2: 3.2+1.05+(All the choices)=7.95
So you do that till the one of the choices equal 7.95.
So overall, it is D. 3.70
110% OF 70 is 77( if you meant of as in multiply)
otherwise...I'm sure its 0.77
sorry if its incorrect
hope I was able to help in some way...
The answer is 29/34 your answer
