According to this paragraph about UVA, tell me how much of UVA's academic budget foes to endowment and gifts?

Context: As of 2013, UVA's $1.4 billion academic budget is paid for primarily by tuition and fees, research grants, endowment and gifts, and sales and services. The university receives 10% of its academic funds through state appropriation from the Commonwealth of Virginia. For the overall university budget of $2.6 billion, 45% comes from medical patient revenue. The Commonwealth contributes less than 6%.

Answer: 19% of UVA's academic budget goes to endowment and gifts.
