The area and the amount of gravel are illustrations of proportions.
7 lb will cover an area of 1 square foot, while 315 lb will cover an area of 45 square feet.
The given parameters are:
The number of pound for an area of <em>1 square foot </em>is calculated as follows:
So, we have:
Cross multiply
Divide both sides by 36
The area to be covered with 315lb gravel is calculated as follows:
So, we have:
Cross multiply
Divide both sides by 252
Hence, 7 lb will cover an area of 1 square foot, while 315 lb will cover an area of 45 square feet.

The equation that best fits the situation is w = 150 * 5 (or the other way around). Since the numbers that would be used are already stated, the equation would be as simple as that. We know that the operation would be multiplication because of the term used "150 for EACH hour" which usually indicates the operation is multiplication.
