The equation y=15x describes the amount of money louis earns, where x is the number of hours he works and y is the amount of money he earns.

the table shows the amount of money carl earns for different numbers of hours works.

how much money does louis earn per hour?

Louis earns $15 an hour. (We know this because 15 * x is the total amount of money he earns.)

Carl earns $12 an hour. (We know this because 36 / 3 is the total amount he get's paid per hour.

Equation for Louis: y = 15x

Equation for Carl: y = 12x

Louis earns more money then Carl.
