You want to sell your house.Your realtor earns 6% of the selling price.Your house sells for 100,000.How much will your realtor e
sp2606 [1]
Hey there! :D

Let's assume that 100,000 is 100%. Now, we have to find what 6% of 100,000 is. 
We can do this step by step.
First, figure out what 1% of 100,000 is. To find 1% of a number, move the decimal place 2 places to the left. 
So, when we move the decimal 2 places to the left, we have 1000.00. Basically, we have 1000.
So, 1000 is 1% of 100,000. Now, to find 6%, multiply 1000 by 6. So, 1000 multiplied by 6 is 6000. The final answer is 6000. The realtor earns 6000 dollars.
Thank you! Hope it helped!

$65 * 20% = $13

Now that we have that, we need to add it to the cost.

$65 + $13 = $78
