A young sumo wrestler decided to go on a special diet to gain weight rapidly
Liula [17]

The weight of wrestler was 80 kg before the special diet

Step-by-step explanation:

Given function is:

W=80+5.4t

We can substitute the values of t to find the weight after t number of months

When we have to find the initial weight , t has to be put equal to zero

So,

W = 80+5.4t\\t = 0\\W = 80 + 5.4(0)\\W = 80+0\\W = 80

Hence,

The weight of wrestler was 80 kg before the special diet
