Acustomer orders a 3.50 slice of pizza, and pays you with a dollar and 9 quarters. did the customer pay you the right amount?

No The customer only paid you or the pizza place 3.25.

Step-by-step explanation:

Because 9*.25=2.25 and there's already a dollar paid so its 1+2.25=3.25 so he is 25 cents off.

if you get paid hourly because if you get a salary you could work all week and only get paid a certain amount no matter how much you work but if you get paid hourly then you get paid for every minute you worked.
