lola has a plant that grows best in temperatures between 20 and 30 degrees celsius.
A.write an iequality that represents the celsius temperatures "c" in which lolas plant grows best.
The equation below is used to convert temperatures from degrees celsisus "c" to degrees fahrenheit"f"
c=5/9(f32)
B.solve the equation "f" in terms of "c"
C. use your answer from part a and b to write an inequality that represents the fahrenheit temperature "f" in which lolas plant grows best.
D. graph your solution on a number line.

A. 20 ≤ best growth≤ 30
B. c = 5/9(f  32)
Multiply both sides by 9/5, then add 32 to both sides to convert to f.
C. plug in the values for c to find f.
D. Can't do this online
