Answer:

147, 168

Step-by-step explanation:

Hi Dequarisefelder!

It's a little hard to understand your question. I think you're asking, however, how many registered voters were Republican and how many were Democrat.

350 * $\frac{42}{100}$ = 147.

So there are 147 registered Republicans

350 * $\frac{48}{100\\}$ = 168.

So there are 168 registered Democrats.

Check:

147 + 168 = 350

So we are correct :D
