Answer:

Explanation:
Given information,
→ Jorge is taking a trip with Bruce.
→ Bruce eats 2 cups of food a day.
Now we have to,
→ Find the required equation.
Let us assume that,
→ d = Number of days
The equation will be,
→ 2d = 12
=> As Bruce eats 2 cups in a day.
Then the value of d will be,
→ 2d = 12
→ d = 12 ÷ 2
→ [ d = 6 ]
Hence, option (a) is correct.
