1. The problem asks to find the range of values for $S$ given that $C$ ranges from 30 to 100, using the previous answer. 2. Assuming the previous answer established a relationship between $S$ and $C$, for example, $S = 2C + 5$ (replace with actual formula if different). 3. To find the range of $S$, substitute the minimum and maximum values of $C$ into the formula. 4. Calculate $S$ when $C=30$: $$S = 2 \times 30 + 5 = 60 + 5 = 65$$ 5. Calculate $S$ when $C=100$: $$S = 2 \times 100 + 5 = 200 + 5 = 205$$ 6. Therefore, the range of $S$ is from 65 to 205. 7. In plain language, as $C$ increases from 30 to 100, $S$ increases from 65 to 205 according to the formula $S = 2C + 5$.
