Luke bought a pair of jeans originally priced at $69.00. The jeans have been marked down 25%, and a sign posted on the rack wher
e he found them says, “10% additional discount given at register.” Which calculation will give the price that Luke will pay for the jeans, not including sales tax? A. 69(0.35)
B. (0.65)
C. 69(0.75)(0.90)
D. 69(0.25)(0.10)
In order to find a discounted price you subtract the discount percentage as a decimal from 1 and multiply the outcome to the original price. For this case, 1-0.25=0.75 and 1-0.1=0.90. So your equation will be 69(0.75)(0.90)
Consider a 3D cardboard box that you can unfold. It would unfold into a 2D net that you can then re-fold back into its 3D form. The 2D net is useful to help visualize and calculate the surface area. The surface area is simply the total area of all the external faces.
