Answer:
He had $ 40 before bought the game.
Step-by-step explanation:
Let x be the original amount ( in dollars ) contained by Ken,
His spending on game = half of his money = [tex]\frac{x}{2}[/tex]
So, the remaining money = [tex]x-\frac{x}{2}[/tex] = [tex]\frac{x}{2}[/tex]
Now, his earning = $ 12,
Thus, final amount he has = remaining amount + earning
[tex]\frac{x}{2}+12[/tex]
According to the question,
[tex]\frac{x}{2}+12=32[/tex]
[tex]\frac{x}{12}=20[/tex]
[tex]\implies x= 40[/tex]
Hence, he had $ 40 before bought the game .
