So im wrong right?

Answer 4

Okay so one bike has two wheels and one seat. One tricycle has one seat but 3 wheels.There are obviously 28 bikes and trikes due to there being 28 seats. We need to equal the wheel out. So let's start with the trikes: One trike has one seat and 3 wheels, as previously mentioned. If there were two, there would be 2 seats, and 6 wheels. 3 would have 3 seats and 9 wheels and so on. So, for bikes, one bike has ONE seat but 2 wheels. 5 bikes would mean he counted 5 seats, and 10 wheels. So, I think you are right. 5 bikes and 23 trikes. 23 trikes would mean 23 seats and 69 wheels. 69 plus 10 equals 79 so we are good there. 23 plus 5 is 28 so we are good there, too.
