Arecord store is having a sale during which all items will be sold at 25% less then marked prices. how much will a cd marked $16 sell for? show work

$12

Step-by-step explanation:

If you're taking off 25% of the regular cost, "taking off" means subtracting.  So if we subtract 25% OF 16, the word "of" means to multiply here.  So our expression then becomes:

16 - .25(16)

16 - 4 = 12

So the CD will sell for $12.

Step-by-step explanation:

The union of two sets contains all the elements contained in either set,

The intersection of two sets contains only the elements that are in both sets.
