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

Luke has a $25 gift card to pay for video game rentals. The first five games he can rent for $3 each. After five games each game cost $1. Which piecewise function best represents the balance remaining on the gift card, f(x), after each game rental, x?

f(x)= 25−3x, 0≤x≤5 f(x)= 15−x, 6≤x≤10

f(x)= 25−3x, 0<x<5 f(x)= 15−x, 6<x<10

f(x)= 25+3x, 0≤x≤5 f(x)= 15+x, 6≤x≤10

f(x)= 25+3x, 0<x<5 f(x)=15+x, 6<x<10

f(x) = { x if x < 4; -x+1 if x ≥ 4

f(x) = { x if x ≤ 4; -x+1 if x > 4

f(x) = { -x+1 if x < 4; x if x ≥ 4

f(x) = { -x+1 if x ≤ 4; x if x > 4
