Let x=amount of monthly sales.

So the first option "Salary of $1950 per month, plus 10% of monthly sales" translates to the equation and the second option "Salary of $2420 per month, plus 6% of monthly sales" translates to the equation

So if you want to find out when option A is better than option B, simply set the left side of option A greater than the right side of option B like this:

Subtract from both sides.

Subtract 1950 from both sides.

Combine like terms on the left side.

Combine like terms on the right side.

Divide both sides by 0.04.

So if the amount of monthly sales is greater than $11,750, then option A is better than option B
