Three investors pool their savings of $330,000 for a motel. If two investors contribute $90,000 and $50,000, what percentage does the third investor represent?

To determine the percentage that the third investor represents, we first need to find out how much this investor contributed. Since the total investment is $330,000 and two of the investors contributed $90,000 and $50,000, we can find the contribution of the third investor by subtracting these amounts from the total.

The combined contribution of the first two investors is $90,000 + $50,000 = $140,000. Then, we subtract this from the total investment:

$330,000 - $140,000 = $190,000.

This means the third investor contributed $190,000.

Next, to find out what percentage this contribution represents of the total investment, we use the formula for percentage:

(Contribution of third investor / Total investment) × 100.

Plugging in the numbers:

($190,000 / $330,000) × 100 = 57.575757...

When rounded to one decimal place, this is approximately 57.6%. Thus, the contribution of the third investor accounts for 57.6% of the total pooled investment, aligning with the correct choice.

Understanding this calculation highlights the importance of recognizing how individual contributions relate to a total amount, which is a
