Question

when ringing up a customer, a cashier needs 10 seconds to process the payment as well as 5.7 seconds to scan each item being purchased. write an equation that shows the relationship between the items being purchased, p, and the time, t. t = blank submit

Explanation:

Step1: Identify fixed and variable time

The fixed time for payment is 10 seconds. The variable time depends on the number of items \( p \), with each item taking 5.7 seconds to scan.

Step2: Formulate the equation

The total time \( t \) is the sum of the fixed payment time and the time to scan \( p \) items. The time to scan \( p \) items is \( 5.7p \) seconds. So, \( t = 5.7p + 10 \).

Answer:

\( t = 5.7p + 10 \)
