Question

In engineering economic analysis, it is permissible to sum dollar amounts without conversion only when __________ .

Answer 1

Answer:

they occur at the same time

Explanation:

What this means is that if let's say on a particular cash record we have two transactions on the same date: For example,

• 11th/20/2020 received $50 from Jude and received $950 from Paul to pay his credit balance.
• 12th/20/2020

Only the two transactions on the 11th are permissible to sum the dollar amounts without conversion.
