80*.5
40
Add this to the original cost
80+40
120
The price will now be 120
1. n-3n=14-4n
n-3n+4n=14
2n=14
n=7
2. -8n+4(1+5n)=-6n-14
-8n+4+20n=-6n-14
12n+6n=-14-4
18n=-18
n=-1
3. -10+x+4-5=7x-5
x-7x=-5+10-4+5
-6x=6
x=-1
4. -6n-20=-2n+4(1-3n)
-6n-20=-2n+4-12n
-6n+2n+12n=4+20
8n=24
n=3

Answer:
Cost of 1 ft²: $7
Cost of 1 ft² of geranium: $6
Step-by-step explanation:
Let x be the cost of a ft² of grass
Let y be the cost of a ft² of geranium
13x + 9y = 145
4x + 12y = 100
x + 3y = 25
x = 25 - 3y
13(25 - 3y) + 9y = 145
325 - 39y + 9y = 145
180 = 30y
y = 6
x = 25 - 3(6)
x = 7
