Jared is putting a new deck off the kitchen. the deck will be 94.45 inches deep. he will use 16 boards that are each 5.7 inches wide. he has to leave a small space between the boards. if the 15 spaces between the boards are all equal, how wide will they be?

16 boards that are 5.7 inches wide each make a total of 91.20 inches.
 
    16
x 5.7
  112
+800
 91.2 inches

Since the deck itself is 94.45 inches deep, we can subtract 91.2 from the number:

  94.45
-91.20 
   3.25 inches.

Finally, we divide 3.25 by 15, since that's the amount of spaces we want and they have to be equal:

3.25/15= .21667

We'll round that to two numbers, so we'll end up with .22.

Your final answer is .22 inches wide for each space.

It is 5.8 you add all of the up to equat 180 then solve the equation
