Each person inflates balloons at different speeds, and they only have 30 minutes to inflate as many balloons as possible. Mary inflates 10 balloons per minute, Jess inflates 7 balloons per minute and Christina came 15 minutes late and was the slowest one inflating 4 balloons per minute.

messages.content: Mary will inflate a total of 10 balloons/minute x 30 minutes = <<10*30=300>>300 balloons
  Jess will inflate a total of 7 balloons/minute x 30 minutes = <<7*30=210>>210 balloons
  Christina will inflate a total of 4 balloons/minute x 15 minutes = <<4*15=60>>60 balloons
  Combining all balloons, they made 300 balloons + 210 balloons + 60 balloons = <<300+210+60=570>>570 balloons
