The formula of the volume of pyramid =1/3*h*base the volume of prism=base*h we know that the height of pyramid is 3 times more than the height of prism so that if the height of prism is a ==> the volume of prism is a*base the height of prism is 3a so that ==> the volume of pyramid is ==>1/3*3a*base=a*base The Answer of the ratio is 1/1
To see how much she saved, you multiply 24.90 x 10 ÷ 100 (or to simplify it 24.90 ÷ 10) you should get 2.49, which you subtract from the original and get $22.41
