# Question 3 of 10
The formula used to convert degrees Celsius to degrees Fahrenheit is $F=\frac{9}{5} C+ 32$.
Convert $68^{\circ} \mathrm{F}$ to degrees Celsius. Solve the formula for $C$, and then use it to convert the temperature.
Which is the correct formula and conversion?
A. $C=\frac{5}{9} F- 32$; conversion: $68^{\circ} \mathrm{F}= 180^{\circ} \mathrm{C}$
B. $C=\frac{5}{9}(F- 32)$; conversion: $68^{\circ} \mathrm{F}= 122^{\circ} \mathrm{C}$
C. $C=\frac{5}{9}(F- 32)$; conversion: $68^{\circ} \mathrm{F}= 20^{\circ} \mathrm{C}$
D. $C=\frac{5}{9} F- 32$; conversion: $68^{\circ} \mathrm{F}= 20^{\circ} \mathrm{C}$

Step 1Let's solve this step by step:
Step 2: Rearrange the original formula F = \frac{9}{5}C + 32 to solve for C
\frac{5}{9}(F - 32) = C
Subtract 32 from both sides:
Final Answer
Option C is correct.
