The town librarian bought a combination of new-release movies on dvd for $20 and classic movies on dvd for $8. let x
represent the number of new releases, and let y represent the number of classics. if the librarian had a budget of $500 and
wanted to purchase as many dvds as possible, which values of x and y could represent the number of new-release and
classic movies bought?
x = 8, y = 45
x = 10, y = 22
x = 16, y = 22
x = 18, y = 18

x= 16 y = 22 and x= 10 y= 22 because the other options would put the librarian over the set budget of $500

Step-by-step explanation:

x = number of new releases

y = number of classics

New-release movies = $20

Classic Movies = $8

x = 8 y = 45 (8*20) + (45*8) = 520

x = 10 y = 22 (10*20) + (22*8) = 376

x = 16 y = 22 (16*20) + (22*8) = 496

x = 18 y = 18 (18*20) + (18*8) = 504

C. x = 16, y = 22

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.
