John has a summer job that pays time and a half for overtime. That is, if John works more than 40 hours per week, his hourly wage for the extra hours is 1.5 times his normal hourly wage of $7. Evaluate choose the correct explanation for p(40)

• John was able to make $280 as a result of working 40 hours in a single week. I found this value by using the first equation in the piecewise function.

• John was able to make $280 as a result of working 40 hours in a single week.I found this value by using the second equation in the piecewise function.

• John worked 40 hours and as a result earned 0 hours of overtime. His overall income was $260.

• John was paid $40 for 280 hours of work.

Luke has a $25 gift card to pay for video game rentals. Which piecewise-defined 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
