Question

The total cost of 3 toys is $\$$0.39. It is represented by the following grid model:


If each toy costs the same, the cost of 1 toy is .

• A. $\$$0.13
• B. $\$$0.23
• C. $\$$0.14
• D. $\$$0.24

Answer 1

The correct option is A $\$$0.13

Total cost of 3 toys = $\$$0.39
∴ Cost of 1 toy = $\$$(0.39 $÷$ 3)

The total cost of 3 toys is $\$$0.39, which is represented using the grid model as:


To calculate the value of 0.39 $÷$ 3, we divide the given model into 3 equal parts:


Dividing 39 blocks into 3 equal parts, we get 13 blocks in each part.

∴ 0.39 $÷$ 3 = 0.13

Calculating 0.39 $÷$ 3 using the standard method, we get:


So, the cost of 1 toy is $\$$00.13.
