The machine will build 24 toys in 216 minutes. We can figure this out by putting it into an equation. This will come out to 15/135 = x/216. Now that we have this, we will have to cross multiply. By doing this, we will now have 135x=3240. Our final step is to to get 1x, and to do this, we divide both sides by 135, giving us 24. I hope this helps
