A project plan charges a fixed monthly fee of $15 and $0.07 per unit. If you process 200 units, what is the total?

• A. $40
• B. $50
• C. $29
• D. $20

Answer: (C)

A plan with a fixed monthly fee plus a per-unit charge means you add the fixed amount to the product of the per-unit price and the number of units. For 200 units, the variable part is 200 × 0.07 = 14. Then you add the fixed monthly fee of 15, giving a total of 14 + 15 = 29. So the total cost is $29. Other options would require different unit counts or pricing—in this case they don’t align with processing 200 units.
