Silver is liquid for Celsius temperatures C such that 960.8 degrees (less than or equal to) C < 2180 degrees. Find such an inequality for for the corresponding Fahrenheit temperatures.

Answer 1

C = 5/9 (F-32)
so, now you have

960.8 <= C < 2180
960.8 <= 5/9 (F-32) < 2180
1729.44 <= F-32 < 3924
1761.44 <= F < 3948
