The amount Lea can earn at her job is shown:
She earns $7 per hour for the first 40 hours. 
She earns 1.5 times the hourly wage for every hour over 40 hours. 
Which piecewise-defined function best represents Lea’s weekly pay, P(h), where h represents the hours worked?

• P(h)= 7h,   0≤h≤40
  P(h)=10.5h−140,   h>40
• P(h)= 7h,   0<h<40
  P(h)= 10.5h−140,     h>40
• P(h)= 7h,     0≤h≤40
  P(h)= 10.5h+140,     h≥40
• P(h)=   7h, 0<h<40  P(h)= 10.5h+140,   h≥40
