This one is a little dificult, Nickolas....
We need to put every thing in terms of yards and then solve for the width
8 ft = 96 in / 36 in = 8/3 yds
4 in = 4/36 = 1/9 yds
So
Length * Height * Width = Total Volume ....so....
L * H * W = Total Volume
(8/3) (1/9) * W =
(8/27) * W
Total cost = Total Volume * Cost per cubic yard
( Note that W will be in terms of yards )
58.07 = [ (8/27] * W * 98
58.07 = W * [8/27] * 98
58.07 = W * [ 784 / 27 ] multiply both sides by 27 / 784
58.07 * [ 27 / 784 ] = W ≈ 1.999 = 2 (yards) = 6 feet
You probably have some questions about this one....it's harder than the others you have submitted
