Question

If it costs 1.85 dollars to rent 3 books at the library, how much would cost to rent 51
books?

Answer 1

To rent 51 books, it would cost $31.85.

Step-by-step explanation:

To find out how much it would cost to rent 51 books, we need to set up a proportion using the given information. We know that it costs $1.85 to rent 3 books, so we can set up the proportion as:

$$\frac{1.85}{3}=\frac{x}{51}$$

Cross-multiplying and solving for x, we find that:

$$x=\frac{1.85\times 51}{3}$$

Therefore, it would cost $31.85 to rent 51 books.
