Final answer:
To calculate the total money raised by the carnival, sum up the income from games and tables and subtract the expenses for decorations and prizes. The total raised is calculated as $1175 in income minus $460 in expenses, which equals $715.
Step-by-step explanation:
The student's question pertains to calculating the total amount of money raised by a 7th-grade carnival after accounting for both income and expenses. To determine how much was raised, the amounts associated with the games and tables are considered income, while the cost of decorations and prizes represent expenses to be subtracted from the total income.
To find the total amount raised:
- Games: $650
- Tables: $525
- Decorations: -$60
- Prizes: -$400
Calculating the sum, we get $650 + $525 which is $1175 in income. Then subtract the expenses for decorations and prizes, which are $60 + $400, equaling $460 in total expenses. Finally, subtract the total expenses from the total income, which is $1175 - $460, to get a net total of $715 raised for the field trip.
The correct answer to the question of how much was raised by the carnival is: a) $715
