Answer:
It cost $36 to the consumer just in materials to re-mulch the area
The dairy produce 8192 cups on average a day
Step-by-step explanation:
Dimensions of area that is needed to be mulch 30 feet by 60 feet.
1 foot = 0.333333 yards
Length = 30 feet = 9.99999 yards
Width = 60 feet = 19.99998 yards
Since we are given that They want a 3 inch layer of much on the area.
1 inch =0.0277778 yards
3 inch = 0.0833334 yards
So, the volume of mulch required for the given area :
= length * width* thickness
= 9.99999*19.99998 *0.0833334
= 16.6666466667 cubic yards
Now 2 cubic yards can be covered with 1 bag of mulch
So, 16.6666466667 cubic yards can be covered with bags of mulch :
=
= 8.33332333335
Thus 9 bags are required to re mulch .
Since cost of 1 bag is $4.00
So, cost of 9 bags = 9*4 =$36
Hence it cost $36 to the consumer just in materials to re-mulch the area
Now,
The dairy produces 512 gallons of milk on average a day.
Now 1 gallon = 16 cups
So, 512 gallons = 512*16 = 8192 cups .
Hence the dairy produce 8192 cups on average a day
