Solve for $F$ : $C = \frac{5}{9}(F - 32)$

F = (9/5)C - 32

F = (5/9)C + 32

F = 9C/5 - 32

F = (9/5)C + 32

Correct Answer: D

Choice Bhoice D is the correct answer.

Start: $C = \frac{5}{9}(F - 32)$
Multiply by 9/5: $\frac{9}{5}C = F - 32$
Add 32: $F = \frac{9}{5}C + 32$

Choice Bhoice C is incorrect because fraction flipped.

Choice Bhoice A is incorrect because sign error.

Choice Bhoice D is incorrect because sign error.
