The label on the car's antifreeze container claims to protect the car between −30°c and 130°c. to convert celsius temperature to fahrenheit temperature, the formula is:
c = 5/9(f − 32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car.

a.) -30> 5/9(f-32)> 130; -22> f> 266

b.) -30< 5/9(f-32)< 130; -22
c.) -30< 5/9(f-32); -22
d.) 5/9(f-32)< 130; f< 266
