Hi guys can i plz get some i don't understand and can i plz get the answers so i can get a 4 on this paper thx

So, Deanna starts with 15 bucks in her pocket, and if she plays 1 game, she then has 15 - 0.75(1), if she plays two games, 15 - 0.75(2), if she plays 3, 15 - 0.75(3), if she plays say "g" amount of games, since each game costs 75 cents, then she would have after "g" games, 15 - 0.75(g) or 15 - 0.75g.

Now, Lise has 13 bucks and her game is 50 cents or $0.50, after say 3 games again she has 13 - 0.5(3) and so on, so after "g" games, she would have 13 - 0.5(g) or 13 - 0.5g.

When with both gals have the same amount?



and surely you know how much that is, since both quantities equal each other, then after that many games, both girls will have the same amount in their pocket.

The slope of the function is 0.5.
