Mr. Swanson bought a package of 10 disposable razors for $6.30. He found that each razor lasted for 1 week. What was the cost per day? Can someone include an explanation too so I can understand it? The unit is unit of rates in class.

0.63 I beleive

Step-by-step explanation:

So when you use your calculator you want to divide 6.30 divided by 10, because there are 10 razors and it is $6.30, so if you wanna know what 1 razor costs, you gotta divide how much money the razors are, and the amount of razors if that makes sense.

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

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.
