Final answer:
The total manufacturing cost of calculators can be calculated using the formula C = 75n + 25,000.
Step-by-step explanation:
The total manufacturing cost of calculators, C, can be calculated using the formula C = 75n + 25,000. This formula takes into account the cost to make one calculator, which is $75, the number of calculators produced, represented by n, and the fixed cost of $25,000. By multiplying the cost per calculator by the number of calculators produced and adding the fixed cost, we can determine the total manufacturing cost.
