Answer:
78.675 pounds
Step-by-step explanation:
36.4 + 42.275 = 78.675 pounds
Consider a function f(x), the linear approximation L(x) of f(x) is given by

Given the quantity:

We approximate the quantity using the function

, where x = 203.
We choose a = 200, thus the linear approximation is given as follows:
Knowing the squareroot of 81 is 9, we can easily know that square root of 83 is close to 9.
9 to the closest tenth is 10.
