__Part ___Whole __New Whole


Solve it: Use a proportion to solve the problem.

Answer 1

To calculate how much money is used to buy reference books, a proportion is set up using the total money and the percentage used for reference books. The calculation yields that $1,440 is spent on reference books from the $4,000 raised.

Step-by-step explanation:

To find out how much money is used to buy reference books, we can set up a proportion based on the percentage given. The whole is the total amount of money raised, which is $4,000. The part we want to find is the amount used for reference books, which is 36% of the whole. The new whole is the actual amount of money spent on reference books.

Step-by-step solution:

1. Set up the proportion: part / whole = percentage / 100.
2. Plug in the values: x / $4,000 = 36 / 100, where x is the amount used for reference books.
3. Cross-multiply to solve for x: 100x = $4,000 * 36.
4. Divide by 100 to solve for x: x = ($4,000 * 36) / 100.
5. Calculate: x = $1,440.

Therefore, $1,440 is used to buy reference books.
