Iposted a picture of the question. needs to be turned in tonight. need asap.

a) How much Carl earns an hour?  $15/h

b) Who earns more per hour? Carol

c) Graphed

Step-by-step explanation:

a) Carl earns $15 per hour.

Earnings per hour can be rewritten as earnings/per

Or earnings divided by hours.

Take a random pair of time and money earned:

$45/3h = $15/1h

Check it with another pair:

$75/5h = $15/1h

b) Carl earns more per hour.

His earnings can be modeled with the equation y = 15x. For every hour he works, he earned 15 dollars.

Louis's earnings are y = 12x, meaning he earns 12 dollars an hour.

15 > 12

c) See picture

Blue is Carl and red is Louis
