Answer provided by our tutors
is your function of Cost, where x is thepercent of people inoculated.
to find the cost of 65% insert 65 into the equation for every x,so
= 260 million dollars
do the same thing for 35% but use 35 instead of 65 in theequation,
= 75.4 million dollars
now subtract the answer for 35% from the answer for 65% 260-75.4 =184.6 million dollars
