Answer: Approximately 72.69 meters
Step-by-step explanation:

To solve this problem you must think in this way.
First we see that function y is greater than 3-x, conclusion is the following
shaded area must be above function. That condition is satisfied by the graph 3 and 4.
Then we write inequality in the slope form y> -x+3.
We see that the coefficient of direction is -1 (negative) which mean that the graph is decreasing. That condition is satisfied by the graph No 4.
The correct answer is graph number 4 ( or D.)
Good luck!!!
The | | sign is called a modulus, it means transform any number inside it to positive, so for example |-2| = 2 but |1| = 1.
therefore, -13 + |-7/4| = -13 + 7/4 = -52/4 + 7/4 = -45/4
