Answer:
<h2>The demand at a price of $1.50 per cone is 44 cones</h2>
Step-by-step explanation:
let us apply the interpolation formula to solve this problem
we have
![\frac{y-y1}{x-x1} =\frac{y2-y1}{x2-x1}](https://tex.z-dn.net/?f=%5Cfrac%7By-y1%7D%7Bx-x1%7D%20%3D%5Cfrac%7By2-y1%7D%7Bx2-x1%7D)
Now let us set the values to the notation above
x= $1.20
x1= $2.20
x2= $1.50
y = 50 cones
y1= 30 cones
y2= ?
![y2= \frac{(y-y1)}{(x-x1)} (x2-x1)+y1](https://tex.z-dn.net/?f=y2%3D%20%5Cfrac%7B%28y-y1%29%7D%7B%28x-x1%29%7D%20%28x2-x1%29%2By1)
Substituting our given data we have
![y2= \frac{(50-30)}{(1.2-2.2)} (1.5-2.2)+30\\\\y2= \frac{20}{-1} (-0.7)+30\\\\y2= (20*0.7)+30\\y2= 14+30\\y2= 44](https://tex.z-dn.net/?f=y2%3D%20%5Cfrac%7B%2850-30%29%7D%7B%281.2-2.2%29%7D%20%281.5-2.2%29%2B30%5C%5C%5C%5Cy2%3D%20%20%5Cfrac%7B20%7D%7B-1%7D%20%28-0.7%29%2B30%5C%5C%5C%5Cy2%3D%20%20%20%2820%2A0.7%29%2B30%5C%5Cy2%3D%2014%2B30%5C%5Cy2%3D%2044)

Answer: 14/35, -32\40, -1
Step-by-step explanation:
Answer:
28 ft squared
Step-by-step explanation:
The 4 sides of a square are equal in length, so if the perimeter is 20ft that means each side would have to be 5ft, (20/4 = 5). If you increase the length by 2ft, one of the sides would now become 7ft (5+2 = 7). If you decrease the length of the other side by 1ft, the length would now be 4ft (5-1=4). Now to find the area, all you have to do is length * width. So you would do 7ft*4ft which is 28ft squared.
You are inversing for subtraction which is addition so D
