Money made for first 35 hours = 14*35 = $490
Money made for remaining hours = 574 - 490 = $84
Extra Hours = 84/21 = 4
Total hours of work = 35 + 4 = 39

Given :
Amount per hour for first 35 hrs = 14
Amount per hour after 35hrs = 21
Amount earned in a week = 574
Let the number of extra hours worked be "x".
Hence we get:
(35x14) + 21x = 574
490 + 21x = 574
21x = 84
x = 4
