Hope it helps!!
The correct answer is Undefined
I just did this in pre-calculus and I’m positive it is correct
Answer:
Todd originally had 64 games; Jaylon had eight.
Step-by-step explanation:
If Todd has 56 games now, after having given eight games to Jaylon, Todd must have started with 64 games.
Let x = Jaylon's original games.
If Todd has <em>250 % more games</em> than Jaylon, he has <em>3.5 times as many </em>games as Jaylon.
Let x = Jaylon's original number of games. Then
x+ 8 = Jaylon's games now
∴ 56 = 3.5(x+8)
Distribute the 3.5 56 = 3.5x +28
Subtract 26 from each side 3.5x = 26
Divide each side by 3.5 x = 8
Jaylon originally had eight video games.
Check:
64 - 8 = 3.5(8 + 8)
56 = 3.5 × 16
56 = 56
