Using the high-low method, we can determine the variable cost per mile and the fixed cost. 
From the data, the highest mileage was 24,000 and the lowest was 12,000. The corresponding operating costs were $35,000 and $23,000, respectively. 
Using the formula: 
Variable cost per mile = (highest operating cost - lowest operating cost) / (highest mileage - lowest mileage) 
Variable cost per mile = ($35,000 - $23,000) / (24,000 - 12,000) 
Variable cost per mile = $1.00 
To calculate the fixed cost, we can use either the highest or lowest data point: 
Fixed cost = Total operating cost - (Variable cost per mile x Total miles) 
Fixed cost = $35,000 - ($1.00 x 24,000) 
Fixed cost = $11,000 
Therefore, the monthly operating costs for 18,000 miles would be: 
Total operating cost = Fixed cost + Variable cost 
Total operating cost = $11,000 + ($1.00 x 18,000) 
Total operating cost = $29,000 
Rounding up to the nearest hundred, the answer is A) $29,330.
