Problema Solution
The percentage, P, of voters who use electronic voting systems, such as optical scans, in national elections can be modeled by the formula P=2.6x + 58.4 where x is the number of years after 1995. In which years will more than 74% of voters use electronic systems?
Answer provided by our tutors
We need to find x such that P(x) = 74, that is:
2.6x + 58.4 = 74 (since P=2.6x + 58.4)

x = 6 years
6 years after 1995 is 1995 + 6 = 2001
In the years after 2001 more than 74% voters will use the electronic systems.
