Answer:

729

Step-by-step explanation:

Given expression:

\sf \dfrac{1}{3^{-2}x^{-4}y^2}

Apply exponent rule \sf \dfrac{1}{a^{-b}}=a^b

\sf \implies \dfrac{3^2x^4}{y^2}

\sf \implies \dfrac{9x^4}{y^2}

Substituting x = 3 and y = -1:

\sf \implies \dfrac{9(3)^4}{(-1)^2}

\sf \implies \dfrac{9 \cdot 81}1}

\sf \implies 729

Ms. Reynolds has 5 stations.

Total time taken will therefore be:

= 8 * 5

= 40 minutes
