Answer (2)
Calculate the total travel expenses by multiplying the travel cost per person by the number of employees.
The travel cost per person is $325 and there are 8 employees.
Multiply $325 by 8 to get the total travel expenses: $325 \times 8 = $2600.
The total cost of travel expenses is $2600 .
Explanation
Understanding the Problem We are given the travel cost per person as $325 and the number of employees as 8. We need to find the total travel expenses.
Calculating Total Travel Expenses To find the total travel expenses, we multiply the travel cost per person by the number of employees: Total travel expenses = Travel cost per person × Number of employees Total travel expenses = $325 × 8
Result of Calculation Multiplying these values, we get: $325 × 8 = $2600 So, the total travel expenses are $2600.
Substituting into the Total Cost Equation The total cost equation is given as: $2 , 880 + $360 + $840 + [ ?] = Total cost We found that the total travel expenses are $2600, so we can substitute this into the equation: $2 , 880 + $360 + $840 + $2600 = Total cost
Final Answer Therefore, the total cost of travel expenses is $2600 .
Examples
Imagine you are planning a business trip for your team. Knowing the travel cost per person, you can easily calculate the total travel expenses by multiplying the cost per person by the number of team members. This helps in budgeting and financial planning for the trip. For example, if each team member's travel costs are $325 and you have 8 team members, the total travel cost would be $325 * 8 = $2600. This calculation is essential for managing expenses and ensuring you have sufficient funds for the trip.
In 30 seconds, approximately 2.81 x 10^21 electrons flow through the device delivering a current of 15.0 A. This is calculated by first finding the total charge in Coulombs and then dividing by the charge of a single electron. The steps involve understanding current, calculating charge, and using the known charge of an electron.
