On $29$ May $1953$, Sir Edmund Hillary, a New Zealand explorer, and Tenzing Norgay, a Sherpa mountaineer from the Nepal, were the first people to climb to the top of Mount Everest. Several attempts had been made since the first attempt in $1921$, but climbing the mountain can be very dangerous. As you go up the mountain, which has an altitude of $8848$ meters, the temperature drops and oxygen levels decrease, leaving explorers exposed to altitude sickness and hypothermia.

If the temperature when Hillary and Norgay left Kathmandu $\left(+5000 \mathrm{m}\right)$ was $-8°\mathrm{C}$, and the temperature drops $7°\mathrm{C}$ for every gain of $1000$ meters, wha temperature would they expect it be at $8000$ meters $($Camp $4)?$ Using integers, write all of the calculations in a single step and evaluate.
