A certain rhino weighs 150 pounds at birth and gains more than 1.2 but less than 2.6 pounds per day during its first year. Which of the following represents the possible weights \(w\), in pounds,
for the rhino 365 days after its birth?
A simple way to do this it to calculate the absolute minimum and maximum weight the rhino could obtain:
Least weight (1.2 pounds per day for 365 days)
$$ w=150+1.2(365) $$
$$ w=588 $$
Greatest weight (2.6 pounds per day for 365 days)
$$ w=150+2.6(365) $$
$$ w=1{,}099 $$
$$ \boxed{588 \lt w \lt 1{,}099} $$
