A company has a maximum advertising budget of \( \$ 100,000 \) for the year. It will be using two different platforms of advertising: online ads and billboards. Each online ad purchased will cost \( \$ 15,000 \) for the year, and each billboard will cost \( \$ 10,000 \) for the year. The company will not spend more than \( 60 \% \) of its overall budget on one of the platforms. 

Given that \( x \) represents the number of online ads purchased and \( y \) represents the number of billboards purchased, create a system of inequalities modeling the scenario. Select all that apply. 

\(\square 15,000 x + 10,000 y \leq 100,000 \) 

\( \square 10,000 x + 15,000 y \leq 100,000 \) 

\( \square 0 \leq x \leq 4 \) 

\( \square 0 \leq x \leq 6 \) 

\( \square 0 \leq y \leq 4 \) 

\( \square 0 \leq y \leq 6\)
