Answer 1

Help????

Answer 2

write equations that express what you know.

let C be the number of children, and A the number of adults.

there are 9 people on the trip. C+A = 9

cost for a child is 210, cost for an adult is 315.

cost per child * number of children (C) + cost per adult * number of adults (A) = total cost (2205)

solve the two equations to get the answers.
