If I asked you is 5 a solution to the equation p +13= 21, how would you determine whether or not 5 works?Plz help I'll mark brainliest Thxs

All you have to do is replace p with 5, and see if it works. In this case it doesn't because 5+13 does not equal 21.

Not a solution

Step-by-step explanation:

You would plug 5 into the equation where it says p. If 5+13=21, then it is a solution. If it equals to something different, then it is not a solution. In this case, it adds up to 18, making it not a solution.

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.
