The answer is: Eli's <span>hot chocolate is more chocolatey.
The explanation is shown below:
The problem says that Arjur adds 20 mL of </span>chocolate syrup for every 3 ounces of hot water and Eli adds <span>45 mL of chocolate syrup for every 3 ounces of hot water.
So, as you can see, the amount of chocolate syrup that Eli adds is greater than the amount of chocolate syrup that Arjur adds (45 mL>20 mL). Therefore, his hot chocolate has more syrup and it is more chocolately.</span>

Answer:
x = 28 m
y = 14 m
A(max) = 392 m²
Step-by-step explanation:
Rectangular garden A (r ) = x * y
Let´s call x the side of the rectangle to be constructed with a rock wall, then only one x side of the rectangle will be fencing with wire.
the perimeter of the rectangle is p = 2*x + 2*y ( but in this particular case only one side x will be fencing with wire
56 = x + 2*y 56 - 2*y = x
A(r) = ( 56 - 2*y ) * y
A(y ) = 56*y - 2*y²
Tacking derivatives on both sides of the equation we get:
A´(y ) = 56 - 4 * y A´(y) = 0 56 - 4*y = 0 4*y = 56
y = 14 m
and x = 56 - 2*y = 56 - 28 = 28 m
Then dimensions of the garden:
x = 28 m
y = 14 m
A(max) = 392 m²
How do we know that the area we found is a local maximum??
We find the second derivative
A´´(y) = - 4 A´´(y) < 0 then the function A(y) has a local maximum at y = 14 m
