Answer 2

Let x be the shortest shelf. The other shelves measures x + 2, x + 4, and x + 6. These lengths should add up to 5 ft or 60 inches
x + x + 2 + x + 4 + x + 6 = 5
The value of x is 12. Therefore, the shelves are 12, 14, 16, and 18 inches long. The longest shelf is x + 6. Thus, the answer is letter C.
