Mercury poisoning is dangerous overload of mercury within the body. A major source of mercury within the body, A major source of
mercury poisoning is consuming fish that contain mercury. Certain fish are more prone to having higher levels of mercury than others. The pie chart shows the distribution of four breeds of fish at a hatchery. The hatchery has approximately 6,000 fish. A biologist from the Centers for Disease Control and Prevention randomly test 5% of each breed of fish for mercury content. Her findings are shown in the following table. Based on the biologist's findings, if a single salmon is randomly selected from those that were tested, what is the probability that this particular fish would have a dangerous mercury level?
A) 0.001

Answer:
A=4000, B=80, C=24
Step-by-step explanation:
You forgot to put the correct area model, I attached it to the answer.
We have the fact that Mountain Q is 4 times the height of Mountain P. That's the "4" we have in the left side of our model. It's like having a multiplication table, next to the "4" we have "A" and upper this we have "1000", the only thing we have to do is multiplify 4*1000=4000. The next letter we have is B and below it we have "320", we divided it by 4, 320/4=80. The last letter we have is C, and is below a "6", we only have to multiplify it by 4, 6*4=24.
At the end we only sum our
- A + 320 + c = 4344 (4 times the height of Mountain P).
- 1000 + B + 6 = 1086(the height of the Mountain P).
