You can choose a couple of the x-values and plug each into all of the x's in each equation on the right. Then see which equations give the y-values equal to the y's adjacent to the 3 x-values you used. I chose x=-4 and x=8. Only the 2nd, 3rd, and 5th equations matched with both.
Convert 8 hours and 15 minutes into minutes- 8 x 60=480 480+15=495
100%-75%=25%
25%=0.25
0.25 x 495 = 123.75 minutes or 2 hour and 3.75 minutes
Hope this helps!!
