Answer:
the equation representing total amount of blood donated is .
Step-by-step explanation:
Total number of volunteers = 32
number of volunteers couldn't donate blood = .
So Number of volunteers who donated blood can be calculated by subtracting number of volunteers couldn't donate blood from Total number of volunteers.
Framing in equation form we get;
So, the number of remaining volunteers who donated blood = .
Each of these volunteers donated blood = 470 ml
Now Total Amount of Blood donated is equal to Amount each of these volunteers donated blood times the number of volunteers who donated blood.
Framing in the equation form we get;
total amount of blood donated milliliters =
Hence the equation representing total amount of blood donated is .

Answer: choice A, graph is moved 7 units up</h3>
The plus 7 at the end will shift the graph 7 units up. Replace y with f(x).
Then we have g(x) = f(x) + 7. Adding 7 to y = f(x) will increase the y value by 7.
