You really have 2 separate equations to solve here:

1) 5(x-1) = - 20        =>     5x - 5 = -20 =>  5x = -15      => x = -3
2) 3y = -15     => y = -5

A boat that costs $8550 decreases in value by 12% per year. How much will the boat be worth after 3 years?
erastovalidia [21]
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

This is a fun problem!  Just graph the two equations, then see what points the line intersects with the parabola.  Or, set the two equations equal to each other, and solve for the two intersecting points.
