One quart of fertilizer covers 300 square feet. to the nearest whole number, how many quarts will danielle need to cover her entire garden? measurements are 20 feet and 24 feet wide.

A = L * W
A = 20 * 24
A = 480 sq ftso her garden is 480 sq ft.

1 qt of fertilizer covers 300 sq ftso how many quarts will cover 480 sq ft.
set this up as a proportion
1/300 = x / 4801 qt to 300 sq ft = x qts to 480 sq ft
cross multiply
(300)(x) = (1)(480)
300x = 480
x = 480/300
x = 1.6so Danielle will need 1.6 qts to cover her garden <==
