Question

there were 32 volunteers to donate blood. unfortunately, n of the volunteers did not meet the health requirements, so they couldnt donate. the rest of the volunteers donated 470 milliliters each. how many milliliters of blood did the volunteers donate? write your answer as an expression.

Explanation:

Step1: Find number of eligible volunteers

The total number of volunteers is 32 and n did not meet requirements. So the number of eligible volunteers is $32 - n$.

Step2: Calculate total blood donated

Each eligible volunteer donated 470 milliliters. So the total amount of blood donated is the number of eligible volunteers times 470, which is $470\times(32 - n)=470(32 - n)$ milliliters.

Answer:

$470(32 - n)$
