There will be 45 adults going and twice as many students
45*2=90 so 45 adults and 90 kids in a 1:2 ratio
Adult tickets cost $25 and kids cost $12
So the total cost of tickets is
45*25=1125
90*12=1080
So the total cost of tickets =$2205
So now they have $295 dollars left. Considering there are only 135 people in their party than they have enough money in their $2,500 dollar budget to each get a $1 dollar ice cream. They'll even have $160 left over
