APPLICATION PROBLEMS - SALE REVENUE PROBLEMS

Sale managers normally want to increase revenue R by selling more. For example, a manager may know by experience that revenue R will increase or decrease according to the following mathematical linear model for a a sales price P and quantity sold Q of a certain commodity: P=Po +-px [This represents a linear equation with positi

Question about Uniform motion

The fundamental formula for such problems is where d represents the distance covered when moving at a speed s during a length of time t. This formula can be solved for s or t (if d is in miles and t is in hours, then s has the units of miles/hour) Smith bicycled 45 miles going east from Durango, and Jones bicycled 7
