For a period of time as an alligator grows, its mass is proportional to the cube of its length. When the alligator's length changes by 15.8%, its mass increases by 17.3kg. Find its mass at the end of this process.

mass=k*length^3
mass+17.3=k(length*1.158)^3
k*length^3=k(length^3 ( 1.55)-17.3
.55K*length^3=17.3
mass*.55=17.3
massfinalthen=17.3/.55 + 17.3
