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

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= ?

Substituting our given data we have

the demand at a price of $1.50 per cone is 44 cones
To find this answer, we need to multiply 3.57 by 12.

Therefore, 12 planks will cost $42.84.
