Hope this helps!

Answer 2

10.8kg

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
