Answer

Explanation:

Step1: Identify initial depth

The initial depth in early - spring is 30 feet below sea - level, represented as - 30 feet.

Step2: Calculate summer depth

In summer, they swim 20 feet deeper. So we add the additional depth to the initial depth: $-30+( - 20)$. Using the rule for adding two negative numbers, $-30+( - 20)=-(30 + 20)=-50$.
