You have set a daily budget of $4,500 and during that day your campaign consumed $3,800. How much will the budget be for the next day?

The correct answer is $4,500 because daily budgets are set for a 24-hour period and do not carry over or accumulate. Each new day starts with the full allocated daily budget, regardless of how much was spent the previous day. The $3,800 spent on the previous day means the campaign utilized part of its budget, but the unspent portion ($700) is simply forfeited for that specific day and does not impact future daily allocations. Therefore, the budget for the next day will reset to the full $4,500. The other options are incorrect because budgets do not become $0 due to underspending, nor do unspent amounts roll over or add to the next day's budget.
