In 2010, the department of defense's overall budget was approximately $534 billion. in the same year, the department of defense budgeted $79.1 billion for research, devel- opment, tests, and evaluations. what percentage of the budget does this represent?

The correct answer is - 14.81%.

The Department of Defense spent 14.81% of its overall budget for research, development, tests, and evaluations.

We can get to the result very easily. We first take the number of the spent budget for the research, development, tests, and evaluations, which is 79.1 billion (for easier calculation we will just use 79.1) and multiply it by 100 (which represents the total amount of percentages).

79.1 x 100 = 7,910.

After we got the number of 7,910, we divided it with the number of the total budget, which is 534 billion (again we will just use 534 for easier calculation), and get to the percentage we require.

7,910 / 534 = 14.81%
