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

−30 > (F − 32) > 130; −22 > F > 266

−30 < (F − 32) < 130; −22 < F < 266

−30 < (F − 32); −22 < F

(F − 32) < 130; F < 266

The formula for converting Celsius to Fahrenheit:
C = 5 / 9 ( F - 32 )
- 30 < 5/9 ( F - 32 ) < 130
9/5 * Ë™(- 30 ) + 32 < F < 9/5 * 130 + 32
- 54 + 32 < F < 234 + 32
-22 < F < 266
Answer:
B ) - 30 < 5/9 ( F - 32 ) < 130;   - 22 < F < 266
