Three friends all live on the same street that runs west to east. Ben lives 7 blocks from Ann. Carol lives 2 from Ben. If the street is represented by a number line and Ann's house is located at 0, what are the possible locations for 's house?

Just use your number line for help but you have to figure out if the numbers are positive or negative.

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

8+(1)(8)

8+8

16

retail price is $16.
