Manuel works at Cheesecake King. He earns $15 per hour as a busboy. The waiters he helps give him 25% of their tips. If Manuel worked 6 hours today, how much did he earn, without tips?

Respuesta :

He earns $15 per hour
For 6 hours, he would earn 15 x 6
= $90

Or

15/1 = ?/ 6

Cross multiply
There ? = 15 x 6 = $90
