You are applying fertilizer to a football field. The field is 360 feet long and 160 feet wide. You use 8 pounds of fertilizer per 1,000 square feet. The fertilizer comes in 50-pound bags. How many bags of fertilizer will you need to complete the job?

Respuesta :

10 bags.

To find this, follow the steps below:

360 x 160 = 60,6000 ft2

60,600/1,000 = 60.6

60.6 x 8lbs = 484.8lb

484.8lb/50lb = 9.696 which is basically 10 bags.

Hope this helps!

Answer:

9.21

Step-by-step explanation:

You first have to calculate the area to fertlize, the formula to do so would be:

A=W*L

Which is the same as

A=360ft*160ft

This will be equal to

A=57,600

You then have to know hom much can you fertilize with a pound of fertilizer.

bags[tex]\frac{1000}{8}=\frac{x}{1}[/tex]

If you clear this equation you´ll have:

[tex]x=\frac{1*(1000)}{8}[/tex]

This equals

x=125

So now we know that you can fertilize 125 squared feet with 1 pound of fertilizer.

Now you divide the total area between the 125 feet.

Amount of pounds need=[tex]\frac{Total  area}{Amount we can fertilize with one pound}[/tex]

Amount of pounds needed:[tex]\frac{57,600}{125}[/tex]

Amount of pounds needed: 460.8

You know that every bag of fertilizer has 50 pounds so you dived the pounds you need by the number of pounds that the bag has.

Bags needed:[tex]\frac{460.8}{50}[/tex]

Bags needed: 9.216
