Everyone would get 3 seeds, you just gotta divided 40 by 12
Answer: $20
Step-by-step explanation:
20% of 25 is 5
You can figure that out by writing 20/100 (percents are out of 100)
Simplified 20/100 would be 1/5
so we are finding 1/5 of 25
1/5 x 25/1 = 25/5 or 5
So the discount is $5
$25 - $5 is $20

Answer: the y intercept is (0, 4)</h3>
=====================================================
Explanation:
We'll need the slope first
Pick any two points from the table and plug them into the slope formula.
I'm going to use the first two rows to get the two points.
m = (y2 - y1)/(x2 - x1)
m = (64-44)/(24-16)
m = (20)/(8)
m = 5/2
m = 2.5
The slope is m = 2.5
Use this slope value with any (x,y) pair in the table. I'll use (x,y) = (16,44)
---------------------
Plug m = 2.5, x = 16 and y = 44 into the equation below. Solve for b
y = mx+b
44 = 2.5*16 + b
44 = 40 + b
44-40 = b
4 = b
b = 4
The y intercept is b = 4
As an (x,y) point, we say the y intercept is (0, 4). The x coordinate of the y intercept is always 0 since x = 0 for any point on the y axis.
The equation y = mx+b turns into y = 2.5x + 4
This is the same as saying y = (5/2)x + 4
To check this equation works, plugging x = 16 should lead to y = 44.
Plugging in x = 24 should lead to 64
Finally, plugging in x = 32 should lead to 84.
I'll let you do this part.
