Which situation cannot be represented by the equation x + 12 = 30?

A. Maria had $12. When she combined her money with Sarah, they had $30. What is x, the amount of money Sarah had?

B. James ran 12 miles on Monday and 30 miles on Tuesday. What is, x, the total number of miles James ran all together?

C. Total snowfall for the winter was 30 inches. In January, it snowed 12 inches. What is x, the amount of snow that fell during the other winter months?

D. Juanita spent $30 at the store buying a shirt and shorts. She bought a shirt for $12. What is the cost, x, of the shorts?

Answer:

B

Step-by-step explanation:

The equation would be 12 + 30 = x, because the amount of miles James ran all together would be the sum (what the numbers add up to).
