The length $L$(in centimetres) of a copper rod is a linear function of its Celsius temperature $C$. In an experiment, if $L=124.942$ when $C=20$ and $L=125.134$ when $C=110$, express $L$ in terms of $C$.

The owner of a milk store finds that, he can sell $980$ litres of milk each week at $₹14/$ litre and $1220$ litres of milk each week at $₹16$ litre. Assuming a linear relationship between selling price and demand, if $k$ litres could he sell weekly at $₹17 /$ litre then find the value of $k$.
