Question

Help Harry to find the cost of the balls.

• A. $8
• B. 0
• C. $80
• D. $10

Answer 1

The correct option is C $80

$\text{Given, the cost of 1 ball}=\$10$

$\therefore \text{The cost of 8 balls =}\$10\times 8$

Let's use the multiplication table to get the value of 10 x 8.


The value of 10 x 8 is the intersection of row number 10 and column number 8.

So, the answer can be shown as:


$\therefore$ The cost of 8 balls is $80.
