Question

• A. $\$3,545$
• B. $\$3,445$
• C. $\$3,454$
• D. $\$3,544$

Answer 1

The correct option is B $\$3,445$

Number of adults enrolled for used comic books $=265$

Price of $1$ used comic book $=\$13$

$\therefore$ Total price of the required comic books$=\$(13\times 265)$

To find out the value of $13\times 265$, we follow the below steps:

$\bullet$ First we write the bigger number at the top and smaller number just below of it with a proper alignment of one's place.


$\bullet$ We first multiply $3$ with $5$, which is $\underset{–}{1}5$, where $1$ is carrying over to the next multiplication, $3\times 6$. So, the next number, we get $(3\times 6)+1=18+1=\underset{–}{1}9$, where $1$ is carrying over to the next multiplication, $3\times 2$. Hence, the last number would be $(3\times 2)+1=6+1=7$.


$\bullet$ For the next multiplication step, we leave one's place (denoted by faded $0$), and start from ten's place.
We first multiply $1$ with $5$, which is $5$. The next number, we get $1\times 6=6$. Finally, the last number, we get $1\times 2=2$.


$\bullet$ Next, we add $795$ and $2650$ to get the final result. Here, $‘‘1+"$ denotes the carry over in addition.



$\therefore 265\times 13=3,445$

Hence, the total price of the used comic books that are required to distribute among interested adults is $\$3,445$.
