Answer 1

Answer:

To forecast by units, you predict how many units you're going to sell each month—using the bottom-up method of course. Then, you figure out what the average price is going to be for each unit. Multiply those two numbers together and you have the total sales you plan on making each month.

Multiplying the unit price by the estimated number of goods or services to be sold. Determining the cost of each good or service. Multiplying the cost of each good or service by the estimated number to be sold. Subtracting total cost from the total sales.
