Answer:
Step-by-step explanation:
Let X is the number of cards Kenny has
Let Y is the number of cards Lee has
1. Kenny had 5/7 more trading cards than lee, it means
X = Y + 5/7X (1)
2. After Kenny collected 50% more trading cards, he had 220 more trading cards than lee, it means:
X + 50%X = Y + 220 (2)
So, we solve the 2 equations to find out X and Y
[tex]\left \{ {{X=Y + 5/7X} \atop {1.5X=Y +220}} \right.[/tex]
<=> X = [tex]\frac{3080}{17}[/tex] and Y = [tex]\frac{880}{17}[/tex]
<=> X ≈181 and Y ≈ 52
