Anita is a waitress and makes P60 per hour plus tips. Her tips average P20 per table. In one 8-hour shift, Anita’s pay can be described by y = 480 + 20x, where x represents the number of tables she waits on. Write a table that shows how much Anita will earn if she waits on 5, 10, 15, and 20 tables. Let x be the number of tables she waits and y be the amount earned in if she waits in x tables. 1. Is this relation a function? Why or why not?
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
