Here is the set up:
(3/4)[(11/8) + (11/9) + (7/8)]
Do the math to find your answer.
(-1, 5) because if you plug in -1 to both equations, you should get 5 from both equations. They also cross at that point, making that the solution.
20% is equal to 0.2
0.2 times 26.40 is equal to 5.28
26.40 minus 5.28 is equal to 21.12
