Answer:
$6000
Explanation:
First you add the freshmen and the adults. Since its $300 per group of 10, you divide the total amount of people that are going (194) by 10. Since you need to have a whole number and can't round to the lowest number you have 20 groups. 20 x 300 = 6000.
176 + 18 = 194
194 / 10 = 19.4
20 x 300 = 6000
