In this question all the details required to solve the problem is already provided. Firstly the fraction given for the amount of paint required needs to be simplified for future use. then we have to get to the problem.
Beth requires 5 1/4 quarts of paint to paint some wall
Cost of 1 quarts of paint = $13.99
Amount of paint required by Beth = 5 1/4
                                                     = 21/4
Cost of 21/4 quart of paint = (13.99 * 21/4)
                                           = 293.79/4
                                           = 73.45
So Beth requires $73.45 worth of paint to paint the amount of wall she desired.
