So here the denominator is 5 and the numerator is 3. If you double 3, you get 6 and to make the fraction equal to 1, you have to make the denominator 6. So we do 6-5 which is 1
2 , -5 , 1
those are the coefficients (C)
For the first bit, put $930 + 7.5x and the second part is 58,000, 930 x 7.5 x 8
the distance between cd rounded to the nearest tenth is ≈ 7
