Since the solution is to be kept between 68° F and 77° F.  

68< F< 77

Putting the value of  F = \frac{9}{5}C + 32 , we have

\Rightarrow \, \, \, 68< \frac{9}{5}C + 32< 77

\Rightarrow \, \, \, 68-32< \frac{9}{5}C < 77-32

\Rightarrow \, \, \, 36< \frac{9}{5}C < 45 

\Rightarrow \, \, \, 36\times 5< 9C < 45\times 5

\Rightarrow \, \, \, 180< 9C < 225

\Rightarrow \, \, \, \frac{180}{9}< C < \frac{225}{9}

\Rightarrow \, \, \, 20< C < 25

the range in temperature in degree Celsius (C) is between  20 to 25.
