OK so first I like to find what 10% is which in this case would be 1.8 and to find the other 5% you divide 1.8 by 2 which gets you .9 if you and 1.8 and .9 you get 2.7 and if you add 2.7 to 18 you get 20.7 which is your retail price
3/5 = 60%
20 ÷ 5 = 4
3 x 4 = 12
Answer is A) 12/20
The correct answer is x = 20
The equation for surface area on a cube is 6 * L^2, where L is side length. Essentially, six squares of equal size
12^2=144
6 * 144=864
I hope you found this both helpful and explanatory
(1.5) decimal form (mixed number form= 1/2-1) hope this helps.
