An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
Approximately 2.81 × 10²¹ electrons flow through the electric device delivering a current of 15.0 A for 30 seconds after calculating the total charge and the number of electrons associated with that charge.

Calculate the total revenue by summing the sales: T o t a l R e v e n u e = 78000 + 182000 + 52000 + 156000 = 468000 .
Calculate the taxes by subtracting transport, wages, and freight from the total expenditure: T a x es = 116600 − 10000 − 13000 − 72800 = 20800 .
The total revenue is 468000 K.
The amount spent on taxes is 20800 K.
Explanation
Understanding the Problem We are given a business budget table with some missing information. Our goal is to find the total revenue and the amount spent on taxes to complete the table. We will calculate these values using the information provided in the table.
Calculating Total Revenue First, we need to calculate the total revenue. The total revenue is the sum of the sales from cabbages, kaukau, carrots, and potato. So, we have: T o t a l R e v e n u e = S a l es C abba g es + S a l es K a u ka u + S a l es C a rro t s + S a l es P o t a t o T o t a l R e v e n u e = 78000 + 182000 + 52000 + 156000 The result of this addition is: T o t a l R e v e n u e = 468000
Calculating Taxes Next, we need to calculate the amount spent on taxes. We know the total expenditure and the amounts spent on transport, wages, and freight. So, we can find the taxes by subtracting these expenditures from the total expenditure: T a x es = T o t a l E x p e n d i t u re − T r an s p or t − Wa g es − F re i g h t T a x es = 116600 − 10000 − 13000 − 72800 The result of this subtraction is: T a x es = 20800
Final Answer Therefore, the total revenue is 468000 K, and the amount spent on taxes is 20800 K.
Examples
Understanding business budgets is crucial in real life for managing personal or company finances. For example, if you run a small vegetable farm, knowing your total revenue from sales and your expenditures on transport, taxes, wages, and freight helps you determine your profit and make informed decisions about pricing, cost-cutting, and investments. By carefully tracking income and expenses, you can ensure the financial health and sustainability of your business.
