The label on the car's antifreeze container claims to protect the car between −40°c and 125°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.

The condition 'temperature between -40°C and 125°C' can be written as inequality -40°C ∠ x°C < 125°C

Formula of changing degree Celcius to degree to degree Fahrenheit is given
°C = 5/9 (°F - 32)
Rearranging to make °F the subject

°F = 

Substitute °C = -40
°F = 

Substitute °C = 125
°F = 

Substitute °F = -40 and °F = 257 into the inequality 

-40°C < x°C < 125°C
-40°F < F < 257°F

Correct B

In this problem it decreased 20%

The equation is y=17(7)+600 and it equals 717
