Total square inches of fabric.
To answer this question you need to know how many square inches makes up one square yard.
1296 square inches makes one square yard.
Therefore total square inches =
1296x4.81= 6233.76 square inches
30% of 42 is 12.6$.
42-12.6 = 29.4$ is the price of the pair with discount applied.

29.4$ + 2.06$ = 31.46 $ final price with discount and tax applied.
They ate 13 hot dogs in 2 minutes, so divide 13 by 2 to find out how many hot dogs he ate in 1 minute:

Now divide total hot dogs eaten by 6.5 to get the total time:
91 / 6.5 = 14 total minutes.
