<p>Is the answer A) or B) ?</p>

<p>because the height is less than 4 on the 4th bounce, 3.88ft, but are they asking for the ft right after the 3rd bounce? It’s hard to explain, when you do the question you’ll understand lol :slight_smile: thanks a lot</p>

<p>The mathematical solution would be:</p>

<p>f(n) = 30(3/5)^n
f(3) = 6…
f(4) = 3…</p>

<p>The ball REBOUNDS to that height after the 4th bounce.</p>
