A motorcycle is depreciating at 15% per year, every year. A student's $15,200 motorcycle depreciating at this rate can be modeled by the equation V(t) = 15,200(0.85). What is an equivalent
equation for this vehicle as a monthly depreciation and, using this equation, what is the motorcycle
worth (rounded to the nearest hundred dollar) 7 years after purchase?
Ov(t) = 15,200(0.8700)12, $13,800
Ov(t) = 15,200(0.9865), $4,900
Ov(t) = 15,200(1.15)-# $5,700
Ov(t) = 15,200(0.9865)12t, $4,900

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
