    Each ordered pair is made up of (h, s), where h = number of hours worked, and s = salary earned.

    The pattern is the hourly salary, $7, times the number of hours. Now the number of hours is h. What is the hourly salary times h?

    h is the variable we chose above to represent the number of hours Tiya worked. For working 1 hour, Tiya earns 7 * 1 For working 2 hours, Tiya earns 7 * 2 For working 3 hours, Tiya earns 7 * 3 For working 4 hours, Tiya earns 7 * 4 etc. For working h hours, Tiya earns _______

    Yes you are correct, but you can't name every different number of hours she works, so we need a general expression to show how much she earns. We use the variable h to represent the number of hours. We have seen that when you multiply 7 by the number of hours, you have what she earned. If she works h hours, she earns 7 times h. 7 times h = 7 * h = 7h

    Remember from part A. s = salary and h = number of hours Tiya worked. s = 7h means that the amount of money Tiya earns is always 7 times the number of hours she works.

    Yes. Part C. is simply: s = 7h
