Question

A young sumo wrestler goes on a special diet to gain weight. The variable w models the wrestlers weight in km after the wrestler has been on a special diet for t months.
w=80+5.4t
How much weight does the wrestler gain every 2 months​

Answer 1

Answer:

10.8kg

Step-by-step explanation:

Before he was on the diet he already weighed 80 kilograms, so it is not important to determining how much weight we gains in two months.  Instead we need to focus on the 5.4t part of the equation.  t represents the number of months so we need to substitute 2 for t and you get

5.4t

5.4(2)

10.8kg
