Respuesta :

Answer:1 pound of fertilizer would cover 125 ft²

Step-by-step explanation:

The label on a 3 1/2 pound bag of fertilizer states that it will cover an area of 437.5 ft.² of lawn. Converting 3 1/2 pounds to improper fraction, it becomes 7/2 pounds.

Let x represent the number of square feet that 1 pound of fertilizer will cover. Therefore,

7/2 pounds = 437.5ft²

1 pound = x ft²

Crossmultiplying,

7x/2 = 437.5

7x = 437.5 × 2 = 875

x = 875/7 = 125 ft²
