Final answer:
Without knowing the individual prices or percentage increases for each car, it's impossible to determine the exact cost increase of the BMW due to inflation; only the combined increase of $11,830 for all three cars can be calculated.
Step-by-step explanation:
The student's question relates to calculating the increase in the cost of a BMW due to inflation. Last year, the combined cost of a BMW, Jeep, and Toyota was $140,000. This year, the cost increased to $151,830. Without specific individual costs for each car, we cannot calculate the exact increase in the price of the BMW. To find the individual increases, information on the price of the Jeep and the Toyota, or their percentage increases, would be required. However, we can say that the combined price increase for all three vehicles due to inflation is $151,830 - $140,000 = $11,830.
