Which of the following examples represents a proportional relationship?

A Wes is making an online purchase. He

B Wendy's cell phone plan is $20 a

club. She pays $10 a month for her
membership but gets her books for $3
each.

215.92 dollars is the answer

no solution

step-by-step explanation:

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
