1. The problem states the equation $9C = 9(F - 32)$ and asks to find the value of $F$ when $C = 100$. 2. Substitute $C = 100$ into the equation: $$9 \times 100 = 9(F - 32)$$ 3. Simplify the left side: $$900 = 9(F - 32)$$ 4. Divide both sides by 9 to isolate $F - 32$: $$\frac{900}{9} = F - 32$$ $$100 = F - 32$$ 5. Add 32 to both sides to solve for $F$: $$F = 100 + 32$$ $$F = 132$$ Final answer: $F = 132$
