The average waiting time on Friday evening is 24 minutes per table. The total waiting time for the 15 tables on Saturday evening is seven and three quarter hours.

Considera la relazione che lega il perimetro \( P \) di un qua- drato e il suo lato \( l \). Verifica che \( P \) e \( l \) sono direttamente proporzionali. Quanto vale la costante di proporzionalità?

\( \left.\begin{array}{l}{f(x)=x^{2}+x+1}\\{g(x)=x+1}\end{array}\right. \)

(I) \( -72 a-(-10 a) \)

The firm uses the following formula to calculate the production output \( (P O) \) \[ P O=5,3 C^{2} L^{15}, \text { where } C=\text { capital invested and } L=\text { labour employed } \] If the capital invested \( (C) \) increases by \( 20 \% \), then the change in \( P O \) will be \( 56 \% \) increase \( 32 \% \) increase \( 44 \% \) increase \( 20 \% \) decrease
