15.) A case of oranges sells at a fruit stand for $5.00. There are 30 oranges in a case. The grocery store sells a case at $8.50. What is the grocery store mark-up?
What is the unit cost at the fruit stand? Unit cost at grocery store?

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.

step-by-step explanation:

just get this app called photo math it should be able to do those

the weight of the object inside the box!
