Doing 1. Determine the function described and then use it to answer the question.
a) A container holds 150 mL of a solution that is 20 mL acid. If n mL of a solution is 60% acid is added, the
20+0.6n
function C(n)
gives the concentration, C, as a function of the number of mL added, n. Express n as
150+n
a function of C.
b) Determine the number of mL that need to be added to have a solution that is 50% acid.
