Why did large states favor representation in congress based on population?

When deciding how the Congress of the United States was going to operate during the Constitutional Convention (1787), two main plans were proposed: the Virginia Plan and the New Jersey Plan. Delegates from different states had to vote on the system that they preferred.

Large states favored representation in Congress based on population, as proposed by the Virginia Plan. The reason for this was the fact that larger states had larger populations, which in turn would give them the right to more representatives, increasing their influence in Congress.
