You can put this solution on YOUR website!
If +t+ = number of teams, they can wash
+5t+ cars in 1 hour
--------------------
If +t+=+3+, they can wash
+5%2A3+=+15+ cars in 1 hour
---------------------------
In 7 hours, they can wash 7 times that many cars
+7%2A15+=+105+
3 teams can wash 105 cars in 7 hours
