# A student buys an algebra textbook for $$\10.35$$, a philosophy textbook for $$\9.72$$, and a dictionary for $$\13.07$$. What is the total cost of the books?

$$\ 33.14$$

Explanation

To get this answer simply add up the costs of the textbooks. $$\10.35 + \9.72 + \13.07 = \33.14$$.
NOTE
A shortcut to quickly answering questions that involve adding decimals is to recognize that the right-most value in the answer (in this case 4) is found by summing the right-most values in the numbers you're adding. 5 + 2 + 7 = 14 which has a right-most value of 4 meaning that the answer will end in 4.
Knowing this trick you can eliminate all answers that don't end in 4 which will often leave you with only one or two possible answers for the question.
