Question

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?

Answer 1

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.
