Answer:
Step-by-step explanation:
we know that
The radius of the circle is equal to the distance from the center of the circle to any point on the circle
the formula to calculate the distance between two points is equal to
we have that the center of the circle is the point (-1,1)
take another point that is on the circle
I take the point (-1,5)
substitute in the formula
Alex bought all the string needed for $125.
It costs $18 for the remaining materials to make each puppet.
So if we closely observe then we see that here $125 is the fixed cost because its not going to change with number of puppets.
And the variable cost is $18.
In this case we can model a Total cost function C(x) for for x number of puppets as below
The total cost to make 50 puppets=$1025
