8 goes into 153 19 times.
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.

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
