The art clup has 18 members. each member must contribute 12.80 every month for supplies. on the first of the month 11 members paid their dues. the remaining members paid on the second day of the month. how much money was collected on the second day of the month?

18×12.80=230.40 (class total)
11×12.80=140.80 (1st day)
230.40-140.80=89.60 (amount paid on 2nd day)

Other way
18-11=7
7×12.80=89.6

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.
