Explanation
There are a few options for solving the given problem. First, you could find out exactly what x equals by setting up an equation: “1,500 is x percent of 300,000” translates algebraically to \(1,500 =\frac{x}{100} (300,000)\).
Solving the equation will reveal that x = 0.5, so the commission is 0.5%. Taking 0.5% of $180,000 gives $900 for Quantity A, which is greater than Quantity B.
Alternatively, you could reason by proportion: \(\frac{1500}{300000} =\frac{c}{180000}\). This works because the
commission the salesman earns represents the same proportion of the total in all cases, so any changes to the total will be reflected in changes to the commission. This gives the same value for Quantity A, $900, and is still greater than Quantity B.
