Jean-Patrick found an old unopened bag of lawn fertilizer in his shed. The bag weighs 36 pounds, and the instructions claim it can cover 10,000 ft^2. If his lawn is 7,000 ft^2, how many pounds will he need? Round to the nearest tenth if needed.

Respuesta :

Answer:

25.2

Step-by-step explanation:

Weight of one bag of  lawn fertilizer = 36

area one bag of  lawn fertilizer can cover = 10,000 ft^2

Total area of lawn in the given problem = 7,000 ft^2

no. of bags of lawn fertilizer needed to cover the lawn = total area of lawn in the given problem / area,  one bag of  lawn fertilizer can cover

                                                             = 7,000/10,000 = 7/10 = 0.7 bags

Weight of full bags has 36 pounds of lawn fertilizer.

therefore,

Pounds of lawn fertilizer in 0.7 part of bag = 36 * 0.7 = 25.2 pounds (Answer)
