To find out after how many hours Joey will make the same amount of money, we can set up an equation. Let's represent the number of hours as "h".
For Family A: Joey earns $40 + $8/hour * h = $40 + 8h dollars.
For Family B: Joey earns $20 + $14/hour * h = $20 + 14h dollars.
To find the point where he makes the same amount of money, we can set up the equation:
$40 + 8h = $20 + 14h
Now we can solve for "h":
40 - 20 = 14h - 8h
20 = 6h
h = 20/6
After simplifying, we find that Joey will make the same amount of money after approximately 3.3 hours.
