Concrete can be purchased by the cubic yard. How much will it cost to pour a slab 17 feet by 17 feet by 2 inches for a patio if the concrete costs $64.00 per cubic yard?

$114.17

Step-by-step explanation:

First we need to convert cubic yard to cubic feet.

One yard is equivalent to three feet, so one cubic yard is 3^3 = 27 cubic feet.

So the cost of one cubic feet is 64/27 = $2.3704

We also need to convert from inches to feet.

One inch is 1/12 feet, so 2 inches is 2/12 = 1/6 feet

Now we need to find the volume of the slab:

Volume = 17 * 17 * (1/6) = 48.1667 ft3

Now, to find the cost, we can use a rule of three:

1 cubic feet -> $2.3704

48.1667 cubic feet -> X

X = 48.1667 * 2.3704 = $114.1743

32/80  

91/140

the last one 54 doesn't go into 45. 54/100 ?
