Answer: C)
Step-by-step explanation: By multiplying 2000 for 1/5, you discover the remaining distance. Considering Mateo swim 3/4 meters per second, dividing the first result for 3/4 will give you the amount of time that he will take to swim what's left (in units of <em>seconds)</em>
For this case we can define the following variables:
x: shirt
y: jeans
We write the following system of equations:
12x + 28y = 3900
8.4x + 35y = 3885
We solve the system of equations:
x = 150
y = 75
Note: see attached image for the solution of the system:

Radius is 8
diameter is 16
curcumference is 50.24
f(x) = 0.5x - money per ticket
g(x) = 8x - tickets per hour
We replace g(x) with its value (8x).
f(g(x)) = f(8x)
We replace the x in f(x) with 8x.
f(8x) = 0,5 × 8x
f(8x) = 4x
<u>⇒ f(g(x)) = 4x</u>
<u></u>
Correct answer:
a.<em> f(g(x)) = 4x, which represents the money Aurora made in dollars per hour</em>
