Best ResponseYou've already chosen the best response.1after \(N\) weeks, Eduardo spends \(7500+300 \cdot N\)

Best ResponseYou've already chosen the best response.1and after \(N \) weeks he earns \(850 \cdot N\), so Eduardo will have a profit if the subsequent condition holds: \[850 \cdot N \geqslant 7500 + 300 \cdot N\] namely earnings are greater or equal than expenses

Best ResponseYou've already chosen the best response.1please you have to solve that inequality

Best ResponseYou've already chosen the best response.1If I subtract \(300N\) from both sides I get this: \[850N  300N \geqslant 7500 + 300N  300N\] please simplify

Best ResponseYou've already chosen the best response.1ok! so we get this inequality: \[550N > 7500\]

Best ResponseYou've already chosen the best response.1I wrote \(>\) because it is better than \(\geqslant \)

Best ResponseYou've already chosen the best response.0so what would I have to do next?

Best ResponseYou've already chosen the best response.1now, we have to divide both side by 550, so we have: \[\frac{{550N}}{{550}} > \frac{{7500}}{{550}}\] please simplify again

Best ResponseYou've already chosen the best response.1ok so we get this: \(1 \cdot N > 13.6363...\)

Best ResponseYou've already chosen the best response.1since the number of week has to be a whole number we can choose N=14

Best ResponseYou've already chosen the best response.0so it would be 14 weeks?

Best ResponseYou've already chosen the best response.1If I call with P the age of Pat and with R the age of Ron, then from the text of your problem, I can write this: \[\begin{gathered} 2P + 5 = R \hfill \\ P + R < 35 \hfill \\ \end{gathered} \]
