Question

An experienced cashier at a grocery store takes 2 seconds to scan each item and 40 seconds to process the customer's payment. 1) If the total time, y, to process a customer's purchase is two minutes and 6 seconds, how many items, x, are being purchased? A) 27 items B) 31 items C) 40 items D) 43 items

Answer 1

The correct option is D) 43 items.

Explanation:

As we know that total given time is ,

`Y = (60*2) +6 =126\hspace{0.15cm} sec`,

Out of which cashier spends 40 seconds to process the customer's payment.

So the remaining time = (126 - 40) = 86 secs.

And the remaining time is used to scan the item and so that we can calculate here the no items scan is = (86 ÷ 2) = 43.

Therefore we can say that 43 items are being purchased.
