Ella was paid an 11 percent commission on the pair of shoes that she sold. The department store had paid $25 wholesale for the shoes and had marked up the price by 40 percent to the selling price. How much did Ella earn for the sale?

The answer is B. $3.85.

Step-by-step explanation:

This is because, first if we get the percentage that the shoes were marked up by, we get that they were marked up to $35, because 40% of $25 is $10 and $25 + $10 = $35.

Then, we find the percentage of $35 that she earned. In order to do this, we see what 11% of $35 is. We get $3.85, because 10% of $35 is $3.50, and 1% of $35 is $0.35. $3.50 + $0.35 = $3.85.

This is why the answer is B. $3.85.

the answer is c. 23/3
