Answer:
Unitary Method
Step-by-step explanation:
If the item is not listed with the unit price we can use different methods to calculate its unit price.
Unit price tells us the cost of each pound, ounce or gram, square foot or meter, etc., of the product.
We can use Unitary Method to calculate the price of each unit. The unitary method is a technique which is used for solving a problem by calculating the value of a single unit, i.e. 1 unit (by dividing) and then finding the necessary value by multiplying the single unit value.
For an instance if a bag of 6 pounds of potato says $7.00, to figure out the price of each pound (that is 1 unit) of potato we can use unitary method:
6 pounds costs $7.00
1 pound costs: dollars.
And that is how we calculate the price of each unit.
