Answer:
The ratio of salmon to total fish caught is 9 over 25.
Step-by-step explanation:
Start with what we know. We have 200 total fish caught and 36% are salmon. The rest is just mumble jumble so don't pay attention to that.
All we have to do is find 36% of 200, and the easiest way to do that is by first knowing that 36% of 100 is 36 so if we double that it will give us 36% of 200.
36 x 2 = 72
So, the ratio of salmon to total fish caught is 72 over 200. But, in simplest form is 9 over 25 because 72/200 divided by 4/4 = 9/25.
Hope this helps! If you have any additional questions please don't hesitate tp ask me or your teacher to be sure you really master this subject. Stay safe and please mark brainliest!

Answer:
The cost of a 12 minute call to France is $ 3.63
Step-by-step explanation:
given:
The cost of 15 minute call to France = $ 4.29
The cost of 10 minute call to France = $ 3.19
To Find :
The cost of a 12 minute call to France = ?
Solution:
Let the flat fee be X
and the cost per minute be Y
so the 15 minute call to France will be
X + 15(Y) = 4.29---------------------------(1)
the 10 minute call to France will be
X + 10(X) = 3.19----------------------------(2)
Subtracting (2) from (1)
X + 15(Y) = 4.29
X + 10(Y) = 3.19
- - -
---------------------------------
5Y = 1.10
--------------------------------
Y = 0.22
So the cost per minute of a call = $0.22
substituting the values in (1)
X + 15(0.22) = 4.29
X + 3.3 = 4.29
X = 4.29 -3.3
X = 0.99
Now the cost of 12 minute call is
=>X + 12(Y)
=> 0.99 + 12(0.22)
=> 0.99 + 2.64
=> 3.63
