Answer 34

If you want to. The 2500 is a fixed cost and each one cost $3. Would you figure the fixed cost in everytime?

Answer 35

the cost of 2500 is fixed and to be paid once.
But 3 is to be paid for each test.
so:

3x+2500

THats the expression for a and the one for b is C=3x+2500/a (the amount of animals)
