Multiple Choice
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
