a record store is having a sale during which all items will be sold at 25% less then marked prices. How much will a CD marked $1
BARSIC [14]

Answer:

$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.
