Multiply the number of adult tickets by the price: 150 x $5 = $750. Multiply the number of student tickets by the price: 200 x $3 = $600. Add the amounts: $750 + $600 = $1350.

Divide the total number of prizes by the number of booths: 35 ÷ 5 = 7 prizes per booth.

The student council has a budget of $2000 for the carnival. They spend $800 on supplies, $500 on food vendors, and $300 on game booths. How much money do they have left?
