An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?

To calculate the Gross Profit, we need to subtract the Cost of Sales from the Sales for each month. Here are the calculations broken down for each month from January to May 2022:
January: Gross Profit = Sales − Cost of Sales = 700 , 000 − 525 , 000 = 175 , 000 Rand
February: Gross Profit = Sales − Cost of Sales = 720 , 000 − 540 , 000 = 180 , 000 Rand
March: Gross Profit = Sales − Cost of Sales = 750 , 000 − 562 , 500 = 187 , 500 Rand
April: Gross Profit = Sales − Cost of Sales = 760 , 000 − 570 , 000 = 190 , 000 Rand
May: Gross Profit = Sales − Cost of Sales = 762 , 000 − 571 , 500 = 190 , 500 Rand
The Gross Profit for each month is calculated by subtracting the respective Cost of Sales from the Sales value. Gross Profit is an important measure as it indicates the efficiency of a company in using its resources to produce goods or services, without taking into account other expenses such as operating costs, tax, etc. Gross Profit helps businesses understand their basic profitability and can be a useful step in determining pricing strategies and cost management.

The electric device delivers a total charge of 450 coulombs in 30 seconds due to a current of 15.0 A. This corresponds to approximately 2.81 x 10^21 electrons flowing through it. This calculation uses the relationship between current, charge, and time, and the charge of a single electron.
