Cds are on sale at the local music store for $12.80 each they normally sell for 16 each ann buys three cds for a total of $38.40 what percent discount did she receive

The discount is 20%.

16  x  3 =   $48.00 regular price for 3 CDs

$48.00 - $38.40 =  $9.60

$48.00  x   20%

48  x  .20  =  9.6

Hope this helps. :)

for a it would be 24 children.

for b i don't understand the question. is it saying for each individual person they pick 5 reds to 7 greens or is it the whole group. clarify and i hope this can you.

step-by-step explanation:

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
