Answer 1

Answer:

Answer: The answer to this problem would be (32-n)*470!

Step-by-step explanation:

Since there were 32 volunteers the beginning and some of them couldn't donate you would subtract (the variable you would use is 'n'). As you may know, each means that you multiply so if each volunteer is giving 470 mm of blood each you would multiply that by how many volunteers are remaining which is unknown.

Your final answer would be: (32-n)*470

Answer 2

Answer:

The volunteers donated  $(15040-470n)$ milliliters of blood.

Step-by-step explanation:

Total number of volunteers was 32 and the number of volunteers couldn't donate blood was $n$.

So, the number of remaining volunteers who donated blood will be: $(32-n)$

Each of these volunteers donated 470 milliliters blood.

So, the total amount of blood donated $= 470(32-n) = (15040-470n)$ milliliters.
