Hello,
do you know what 6% equals in decimal?
With such information, all you must do is multiply the decimal value of 6% to 8000, then add that value to 8000 for the markup value.
Answer:
(a)3>2n<17
(b)3+2n=-1
(c)-2,16,15,14,13,12,11,10,9,8,7,6,5,4,3,2,1,-1,-2,-3,-4
A = πr². So, 14 / 2 = 7 inches (radius). A = (3.14)(7)² || A = (3.14)(49) || A = 153.86 Inches ². Hope this helps!
