 Math Central Quandaries & Queries
 Question from kelly: I have an existing amount of $22,750.00. this includes the profit at 10% and overhead at 10%. How do I remove the profit and overhead in order to come up with the original starting figure? Hi Kelly, I would start by assuming you know the original starting figure and that you can use some algebra. Suppose the original starting price is$\$S.$. You add 10% for profit and 10% for overhead so you are adding 20%. Thus

$\S + 0.20 \times \S = \22,750.$

Thus

$1.20 \times \S = \22,750.$

Now the algebraic step. Divide both sides by 1.20 to get

$\S = \frac{\22,750}{1.20} = \18,958.34$
