Paul plans to put concrete on a rectangular portion of his driveway. The portion is 12 feet long and 6 inches high. The price of concrete is $98 per cubic yard. The total cost of the concrete Paul needs is $108.89. Which of the following is closest to the width of the portion of the driveway on which Paul plans to put concrete?

[1 foot = 12inches; 1 yard = 3 feet]

Answer 1

Hi,
1 cubic yard = 27 cubit feet

then we must find the no.of cubic yards ....
for 1 cubic yard = $98
for "x" cubic yard = $108.89

1/x =98/108.89
x = 1.11112

Now we have to convert this in to cubic feet...
1 cubic yard = 27 cubic feet
1.11112 cubic yard = x cubic feet

1/1.11112 = 27/x
x = 30.0024 cubic feet

now
width x height x length = 30.004 cubic feet
w x 12 x (1/2) = 30.004

w = 30.004/6
= 5.0004 feet

yep! there for the width of the yard is approximately 5 feet..

hope this will help ya !
