Under normal conditions, the atmospheric temperature drops 3.5°F per 1000 feet of altitude up to 40,000 feet. When the outside temperature is 80°F, the atmospheric temperature can be modeled by t(x) = − 3.5x + 80, where x is the altitude in thousands of feet. Find value of x so that t(x) = − 25.
x = 30
