Question

A young sumo wrestler goes on a special diet to gain weight.

The variable w models the wrestler's weight (in kilograms) 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



Explanation:

w= 80 + 5.4t

At time 0, when he starts the special diet to gain weight, his initial weight is

w = 80 5.4(0)

w = 80 + 0

w = 80

Initial weight of young sumo wrestler = 80 kg.

After 2 months, t = 2.

His weight is

w = 80 + 5.4t

w = 80 + 5.4(2)

w = 80 + 10.8

w = 90.8

Weight of young sumo wrestler after 2 months = 90.8

kg.

His gain in two months was 90.8- 80 = 10.8 kg

10.8 kg
