Pick numbers

x=2

James gets paid 40*2 + 2(2) = 84

Harry gets paid 30*2 + 3 * extrahours = 84

extrahours = 24/3=8

Harry worked 30+8 = 38 hours

James worked 41 hours => 40x (regular pay) + 2x (for the extra one hr)

Harry to get 42X dollars,

=> 30X (for regular 30 hrs) + 12X/1.5X (extra hr pay rate)

=> 30 + 8 => 38
