Final answer:
To stay within the $8000 budget after spending $3400 on transportation, all other costs for the field trip must be no more than $4600.
Step-by-step explanation:
To calculate how much more the student group can spend on other costs for the field trip while staying within their $8000 budget, we need to subtract the cost of transportation from the total budget.
Since the transportation costs $3400, we can calculate the remaining amount for all other costs, C, using the following equation:
C = Total Budget - Cost of Transportation
Substituting the given values into the equation:
C = $8000 - $3400
Performing the subtraction:
C = $4600
Therefore, all other costs must be no more than $4600 to stay within the budget.
