The 8% the problem is referring to is referring to 8% of 12. If we were to multiply the decimal version of 8%, which is 0.08, by 12, we can find what 8% of 12 is. The product of those two numbers is 0.96, which is equal to $0.96. Now we can add this amount to the original price of $12. Therefore making the total new price of the basket $12.96.
Find the surface area by base x height x2 for the triangles then. 8 squared plus 10 squared equals hyp squared which would give the slope measure. so the multiply that by 8 to get the slope area and the 8 x 8 to get the back hope this helps.
