Answer = £15347.06
100 - 19.5 = 80.5
80.5 / 100 = 0.805
19064.67 x 0.805 = £15347.06
Division because if you divide the two functions together, you keep the 3 in the x term. If you add the two functions, your coefficient is 6. If you subtract, the x term is eliminated. If you multiply, you'll get 9x.
3 is smaller than 6 or 9 :)
First add 10 on both sides. So it will be v = 1.
