extra_info.answer: Billy has a salary of $10+0.50+$1.00=$<<10+0.5+1=11.50>>11.50 per hour.
  Sally is paid $0.50 more per hour than Billy's initial salary, for a total of $10+$0.50=$<<10+0.5=10.50>>10.50 per hour.
  If Billy works 20 hours, he will be paid 20*$11.50=$<<20*11.5=230>>230
  If Sally works 20 hours, she will be paid 20*$10.50=$<<20*10.50=210>>210.
  Thus, if both work 20 hours, Billy will be paid $230-$210=$20 more.
  #### 20
