Revenue and Range Calculations

The video tutorial covers four math problems. Problem 129 involves calculating the range of miles per gallon for Cindy's car using rounded values. Problem 130 deals with solving an inequality using absolute value on a number line. Problem 131 calculates the number of women needed to increase the percentage of women workers in a factory. Problem 132 finds the average daily revenue for a snack shop over a 10-day period.
