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
2860 times .12 equals $343.20
The slope--- 5.2x represents how much income is increased based on the worker's experience year
the y-int ------ 22 represent if the worker has no experience then he gets $22 income
b) the way you can tell the cost of income in 19 years is to estimate it using your ruler or just eyeball it
I'm sure you don't need this becuz u post this question a week ago
