Question
One box of donut cost $10. 3 boxes of donut cost are?
- 30
- 40
- 50
- 60
Hint:
The values in multiplication get very large very quickly. When you 'multiply' or 'times' a number you add it to itself a number of times, for example 3 multiplied by 4 is the same as saying 3+3 +3 +3 = 12. Multiplication is therefore a quicker way of adding the same number many times, for example 3 x 4 = 12.
The correct answer is: 30
The cost of one box of donut is 10 and we have to find the price of 3 boxes of donut.
The price of one box of donut is = $10
For the price of 3 boxes of donut = 3 x (price of one box of donut)
= 3 × ($10)
= $30
Therefore, cost of 3 boxes of donut is $30.
In short way,
One box of donut cost $10.
3 boxes cost =?
3 × 10 = 30.
3 boxes of donut cost are $ 30.
