Solve the problem.A political poll has a built in error tolerance. A candidate receiving 41% support, according to the poll, could actually have 43% support and the poll would still be considered accurate. The error tolerance for the candidate with 41% support is 3%. An acceptable percentage p for the candidate must satisfy the inequality 
? 3. Solve the inequality and interpret the result.
A. {p
};Actual support for the candidate could vary between -3% and 3%.
B. {p
}; Actual support for the candidate will not vary because you cannot have negative percentages.
C. {p
}; Actual support for the candidate could vary between 41% and 44%.
D. {p
}; Actual support for the candidate could vary between 
and 44%.
