Aldo wants to rent a boat and spend at most $81. the boat cost $7 per hour, and Aldo has a discount coupon for $3 off. what are the possible numbers of hours Aldo could rent the boat?

Respuesta :

we have the following inequality

[tex]\begin{gathered} 7t-3\le81 \\ 7t\le84 \\ t\le12 \end{gathered}[/tex]

so he can rent the boat for at most 12 hours. It means that the possible numbers are 0,1,2,3,4,5,6,7,8,9,10,11,12
