Question 199222: I try to see if one of these problem was already done and it was not please help Asap.. Thank you in advance.

Sam wishes to fertilize his lawn that is 16 yards by 70 yards. The organic fertilizer costs 5.75 per bag. Each bag covers 525 square feet. What is the cost to fertilize his yard?

First find the area of the rectangular lawn:
A+=+%2816%29%2A%2870%29
A+=+1120 sq.yds. Next, convert this into sq.ft by multiplying by 9 sq.ft. per sq.yd.
A+=+%281120%29%2A%289%29
A+=+10080sq.ft. Now divide this by 525 sq.ft to find the number of bags (B) of fertilizer required.
B+=+10080%2F525
B+=+19.2 Round this the nearest integer since you can't buy fractional bags of fertilizer.
B+=+20bags. Finally, multiply the number of bags (20) by the cost of each bag ($5.75) to get the total cost (C) of fertilizing the lawn.
C+=+%2820%29%2A5.75%29
C+=+115
The total cost that Sam will pay is $115.00 and he will have some fertilizer left when he's finished.
