Use reasoning to answer the following question.
Eliza has 4 siblings. The total height of all 5 siblings combined is 330 inches. Two of her siblings are both 66 inches tall. Another sibling is 60 inches tall. If Eliza is 2 inches shorter than the last sibling, how tall is Eliza?

68
The first three siblings are 66 + 66 + 60 = 192 inches tall.

Since the total of all the siblings is 330 inches, Eliza and the last sibling are 330 - 192 = 138 inches tall combined.

If Eliza's height = h, 138 inches = h + (h + 2).

(138 - 2) / 2 = 68 inches.

Eliza is 68 inches tall.

The answer: 68
