Answer

Fahrenheit: $50 \leq F \leq 95$ Celsius: $10 \leq C\leq 35 $

Work Step by Step

It says that the laptop computer can operate within a temperature range of 50F to $95F$: $50 \leq F \leq 95$ The transform between Fahrenheit and Celsius is given by: $C=\frac{5}{9}(F-32)$ Hence, we get the inequality in Celsius: $\frac{5}{9}(50-32) \leq C \leq \frac{5}{9}(95-32)$ $10 \leq C\leq 35 $
