Let x be the number of hours
DJ Joe 0 + 100.00 x
DJ Dan 150 + 75.00 x
For 2 hours
DJ Joe 0 + 100.00 * 2 = 200
DJ Dan 150 + 75.00 * 2 = 300
For 8 hours
DJ Joe 0 + 100.00 * 8 = 800
DJ Dan 150 + 75.00 * 8 = 750
Better deal
DJ Joe < DJ Dan
0 + 100.00 x < 150 + 75.00 x
0 + 100.00 x < 150 + 75.00 x
0 - 150 < 75 x -100 x
-150 < -25 x
6 > x
x should be less than 6 hours
