This question states that Lake Lopez began at a depth of 515 inches, then increased by 82 inches, then decreased by 119 inches. To model this, we will use addition for the increase and subtraction for the decrease; this will signify a positive/negative change in the depth. This can be modeled by the expression below:
515 + 82 - 119
597 - 119
478
Therefore, the water depth at the end of the summer was 478 inches.
Hope this helps!

Step-by-step explanation:
Plug in the values of X on the left side of the table into the function on the right side of the table. Remember that negative exponents mean the number is under a fraction. 4^-0 is like saying one over 4^0.
For the blue table, because the numbers are already in a fraction and in parentheses, you apply the exponent to each number individually.
