Fa-g=a, solve for the letter a

a = a + g/f

Step-by-step explanation: To get a by itself, we first isolate

the a term by adding g to both sides to get fa = a + g.

Next, we divide both sides by f and we have a = a + g/f.

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.
