1. Since the coat is on sale for 22% off you want to do 300 times 0.22 to get 66. With this number you are going to take 300-66 to get $234.
2. The formula for the volume of a rectangular pyramid is V= lwh/3
Since I know that the total volume is 120 I know that the l times w time h has to equal 360 since its divided by 3. With the 12 and 5 I get 60. Since I know that 360/60 equals 6 I know the answer is B.
So you have to multiply 300 times 22 which equals which equals 6600. So now you have to divide 6600 by 100 which your final answer is 66. Hope this helped!
