Answer:

c = $\frac{1}{10}$

f= 1500

Step-by-step explanation:

Tenemos la siguiente ecuación

$C = f+cm$

Tenemos los siguientes valores para m=15000, c = 3000 y para m = 20000, c=3500. Es decir, tenemos las siguientes ecuaciones

$3000=f+c15000, 3500=f+c20000$

Si restamos la segunda ecuación de la primera, tenemos que

$3500-3000 = f-f+(20000c-15000c)$

Luego

$500 = 5000c$

Entonces $c = \frac{500}{5000} = \frac{1}{10}$

Si tomamos la primera ecuación, tenemos que $3000-\frac{15000}{10} = f$ . Es decir,

$3000-1500 = f = 1500$

Esta solución, al plantear 2 ecuaciones y dos incógnitas, plantea un sistema dos por dos.

Jake went on a riverboat tour. After returning from the tour, he was curious to know the speed at which the boat was going. Duri

I'm sorry I'm too lazy to read all of that. However, I did get the main point. The river was going at 3 mph. Since he wanted to travel 10 miles upstream and downstream, you would have to subtract 20 by 3. This would mean he was going at a speed of 17 mph.
