Wallet A is 1" thin.
Wallet B is twice as thin as wallet A.
Write a mathematical expression describing the thinness of Wallet B, solve. Show all work.
Extra credit:
Wallet A costs $100 in department stores.
Wallet B is not available in stores but if you act now, can be ordered by phone for the low low price of twice as less as the competitor Wallet A.
solve for the price of Wallet B.
But Wait! If you order now, you get a second twice as thin wallet!
now, solve for the price of Wallet B (A) and Wallet B (B).
but that's not all! If you order in the next 30 seconds you'll also receive a can of aerosol tar spray and 6 lint free cloths, and on qualifying orders, a bucket of imitation sea shells.
Solve for the price of all that crap individually.
