Retirement Eligibility and Voting Percentages

The video tutorial covers four math problems. Problem 92 involves calculating Nancy's total sales based on her earnings, using percentages. Problem 93 requires finding the value of x that keeps the median of two lists equal. Problem 94 calculates the percentage of voters expected to vote for a candidate, using given percentages of Democrats and Republicans. Problem 95 determines the earliest year a female employee can retire based on a rule of 70, considering her age and years of employment.
