A real estate agent normally charges 4% commission to the seller. To make an offer of $172,000 seem more attractive to a seller, she reduced her commission to 2.25%. How much did the seller save?

The amount saved is $3,010

Step-by-step explanation:

Here, we want to calculate the amount saved

On the normal 4%, the amount charged is

4/100 * 172,000 = $6,880

For the 2.25%, we have

2.25/100 * 172,000 = $3,870

The amount saved is thus;

$6,880-$3,870

= $3,010

answer: d. $20
