Solution

The correct option is B $2,100
Cost of one book =$15
Total number of books Maria wants to buy =140
Amount that Maria needs to pay to buy 140 books =140×$15

This product can be evaluated as:

First, we need to multiply the units digit, i.e., 5 with 140.

Now, we would multiply the tens digit, i.e., 1 with 140.


Now, we would add 700 and 1400 to get the answer.



The amount that Maria needs to pay to buy 140 books would be $2,100.
