Identify Volunteers and Blood Amount: Identify the total number of volunteers and the amount of blood each volunteer donates. $\newline$ Total number of volunteers: $32$ $\newline$ Amount of blood donated by each volunteer: $470$ milliliters
Determine Donating Volunteers: Determine the number of volunteers who were able to donate blood. $\newline$ Since $n$ volunteers could not donate, the number of volunteers who did donate is $32 - n$ .
Calculate Total Blood Donated: Calculate the total amount of blood donated. $\newline$ To find the total amount of blood donated, multiply the number of volunteers who donated by the amount of blood each donated. $\newline$ Total blood donated = $(32 - n) \times 470$ milliliters
Write Expression for Total Blood: Write the expression for the total amount of blood donated. $\newline$ The expression for the total amount of blood donated is $(32 - n) \times 470$ milliliters.
