Svetach [21]

Answer:

<em>3p + 89 < 765</em>

<em>Correct answer: D.</em>

Step-by-step explanation:

Austin, his dad, and brother make a group of three people of varying weights. Assume their average weight is p and their total weight 3p.

The cooler and other supplies weigh 89 pounds in total.

The weight of the supplies and the three people in the canoe should not be equal or exceed the maximum allowable weight of the canoe of 765 pounds.

This leads to inequality:

3p + 89 < 765

Correct answer: D.
