I know if 5 teacher travels for 7 nights its 7200 How will I find how many students

4. DrBob222

You're absolutely right. \$7200 is the cost for 7 nights for 5 adults. How much is the cost for 7 nights for 1 student? Then go from there to see how many students could go for the adults' cost.

5. help

420\$ for 7 nights for one students + 600 which is 1020

7200 = 1020

6. DrBob222

I figured 7.05 but of course you can't chop up the students to get 0.05 of one of them so 7 would be correct. And there is a little money left over. See, you were able to do large parts of this.
