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 over 9 (F − 32). Write and solve the inequality to determine the Fahrenheit temperature range at which this antifreeze protects the car.

−30 > 5 over 9 (F − 32) > 130; −22 > F > 266 −30 < 5 over 9 (F − 32) < 130; −22 < F < 266 −30 < 5 over 9 (F − 32); −22 < F 5 over 9 (F − 32) < 130; F < 266
