You have to take $8,550 times 0.12 (12%) to find out the number it is being decreased by. 8,550 x 0.12 = 1,026 And then, you have to subtract 1,026 from 8,550 three times for three years and your answer becomes 5,472. $5,472
To find x, you divide both sides of the equation by 12.20. This would look like this: 12.20x/12.20 =372.10/12.20 . Then, the answer you get is 30.5, so. X=30.5
