Sharona has a free membership to an online shopping club called The Big
Save where she orders for her company. She only ever buys one thing from
them, industrial bottles of bleach. The Big Save charges the same amount
for shipping no matter how much you order.
If she purchased 2 bottles at a cost of $13.00 one month, then paid $33.00
for 10 bottles...
What is the cost per bottle of bleach?
(write in dollars and cents form, ex. $x.xx)
