When ringing up a customer, a cashier needs 19 seconds to process payment as well as 1 second to scan each item being purchased. If it takes 26 seconds to ring up a customer, how many items are being purchased?
Step-by-step explanation: Since 19 seconds alone are being used to ring up a customer, you do 26-19, which equals 7. If it takes 1 second to ring up each item, it would be 7 seconds. Hope this helped!
