The surface area of the cube is 600cm^2.
6(10^2)
6(100)
600
First, you would multiply $210 by 20%
This is done by converting 20% to a decimal, .2
So, 210 • .2 = 42
Then to find the sale price, you would subtract that 42 that you just got from 210,
and you get $168 as the final sale price.
Keep adding by the same value everytime so start with 10,000 then add 20,000 etc
