A student is measuring the oven's temperature using a K$-$type thermocouple connected to a high$-$precision voltmeter. The cold junction of his thermocouple is placed in a container with a mixture of ice and water. The voltmeter shows the reading of $2\mathrm{.}073$ mV$.$ Determine the temperature of the oven using the firstorder Newton interpolation. $($Two decimal places$)$
