The function c(x) = 350x represents the cost c of buying a customized bag where x stands for the number of bags.   How much is the cost for 5 bags?

To find the cost of 5 bags using the function $ c(x) = 350x $, substitute $ x = 5 $ into the equation:

\[
c(5) = 350 \times 5
\]

\[
c(5) = 1750
\]

So, the cost for 5 bags is **$1750**.
