Concept:The percentage of the GDP contributed by the mining sector is calculated by multiplying the total GDP by the given percentage.Explanation:The total GDP is given as $\$540$.The mining sector contributes $60\%$ of this total.First, write the percentage as a fraction:$60\% = \dfrac{60}{100} = 0.6$Now multiply the total GDP by this fraction:$\text{Contribution} = 60\% \times \$540$$\text{Contribution} = 0.6 \times \$540$Compute the product:$0.6 \times 540 = 324$Therefore, the mining sector contributes $\$324$ to the GDP.This corresponds to option C.Answer:C. $\$324.00$
