Answer:

The temperature of the chemical solution after t hours is
$-14.96-2.9t\;^(\circ)C$

Explanation:

Given that the initial temperature of the chemical solution,
$T_0= -14.96^(\circ)C$ .

The rate of decreasing temperature,
$R = 2.9^(\circ)C/ hour$

So, after t hours, the temperature of the chemical solution will decrease by
$Rt=2.9t^(\circ)C$ .

So, the temperature of the chemical solution after t hours,

$T=T_0-Rt \\\\\Rightarrow T = -14.96-2.9t\;^(\circ)C$

Hence, the temperature of the chemical solution after t hours is
$-14.96-2.9t^(\circ)C$ .
