A = L * W
A = 20 * 24
A = 480 sq ft.....so her garden is 480 sq ft.
1 qt of fertilizer covers 300 sq ft....so how many quarts will cover 480 sq ft.
set this up as a proportion
1/300 = x / 480....1 qt to 300 sq ft = x qts to 480 sq ft
cross multiply
(300)(x) = (1)(480)
300x = 480
x = 480/300
x = 1.6.....so Danielle will need 1.6 qts to cover her garden <==

Use a calculator :)
Answer:
Others 2367
Students 481
Step-by-step explanation:
Let x be students and y be others
x + y = 2848
x = 2848 - y...............(1)
2.50x + 3.75y = 10078.75
Substituting,
2.50(2848-y) + 3.75y = 10078.75
y = 2367
x = 2848 - 2367 = 481
ok.
200-14d<80
-14d<80-200
-14d<-120
d<-120/-14
if you divide the other side with a negative the sign has to change.
d>-120/-14
d>120/14 (both signs are negative making it positive)
d>60/7 (making it into its simplest form by dividing both by 2 as its is the only possibility)
or d>8.57142857143
