Question

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 1000 square feet. The fertilizer comes in 50- pound bags. How many bags of fertilizer will you need to complete this job?

Answer 1

10 bags of fertilizer for the field

Answer 2

10 bags

Explanation:

Length of field = 360 feet.

Width of field = 160 feet

Area of field =
`Length * Width`

=
`360 * 160`

=
`57600 feet^2`

Amount of Fertilizer used for 1000 sq.ft. = 8 pounds

Amount of Fertilizer used for 1 sq.ft. =
`(8)/(1000)`

Amount of Fertilizer used for 57600 sq.ft. =
`(8)/(1000) * 57600`

=
`460.8 pounds`

50 pounds = 1 bag

So, 1 pound =
`(1)/(50)`

So, 460.8 pounds =
`(1)/(50) * 460.8=9.216`≈ 10

So, 10 bags will be required to complete the job.
