how would a company use algebra to compare sales and profits?

Question

exm: tables, graphs and equations

Answer 1

Sales less Cost of Goods, (COGS) = Gross Profit
Gross Profit divided by Sales = Gross Profit %.

The equation might look like this.
(Sales less COGS) / Sales =GP %, as an algebraic equation to get GP % in one step.
The / is used as division.

To compare this year, increase over last year.
(TY less LY) / LY = % increase , or decrease.

To determine the Selling Price with a desired markup of 40%.
Cost / (100% - 40%) = SP.
This takes the complement of 40% to 100% =60%.
By dividing the cost by 60%, the SP is determined.

You can prove this by, multiplying the Dividend by 60%, and the cost is the result. And so, 40% is the gross profit.
Added together, will = the SP.
This will work with any desired profit %.

Tables can be built around these functions. Graphs can be generated by using any or all.
