Interpret eigenvalues in long-term models - calculation checkpoint

A school canteen growth matrix has dominant eigenvalue \(1.08\). If the long-term pattern has scaled to 76 units this year, estimate the corresponding scaled amount next year. This version asks for the same mathematical quantity after confirming the method from the context. Enter the requested value and choose the interpretation that matches the result.
