Question
If the cost of 8 cans of juice is $240, the cost of 4 cans of juice is __________.
- $120
- $60
- $160
- $80
Hint:
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
The correct answer is: $120
Here, we are given that the cost of 8 cans of juice is $240. We have to find the cost of 4 cans of juice.
We have,
Cost of 8 cans of juice = $240.
Then, cost of 1 can of juice = $240⁄8 = $30.
So, the cost of 4 cans of juice = 4 × 30 = $120.
Hence, the correct option is A.
We can also find the cost of 4 cans of juice by just dividing the cost of 8 cans by 2.
