The rate of change of the equation is 5.4 kilograms per month. To find the weight gain, we can multiply the rate of change by 2, the number of months. :)
A young sumo wrestler decided to go on a special diet to gain weight rapidly. W(t) models the wrestler's weight (in kilograms) as a function of time t (in months). W(t)=80+5.4t
What was the wrestler's weight before his special diet?
Again the function is W(t)=80+5.4t,
We know that W is the weight while t stands for time in months
