Question

When ringing up a customer ,a cashier needs 27 seconds to process payment as well as 4 seconds to scan each item being purchased .If it takes 43 seconds to ring up a customer, how many items are being purchased

Answer 1

Answer:

The number of items are being purchased is 4 .

Step-by-step explanation:

Given as :

The time taken to process the payment = 27 seconds

The time taken to scan each items = 4 seconds

The total time taken to ring up a customer = 43 seconds

Let The number of items being purchased = n

Now, According to question

The total time taken to ring up a customer = The time taken to process the payment + The time taken to scan each items × The number of items being purchased

i.e 43 =  27 + 4 × n

Or, 4 × n = 43 - 27

Or,  4 × n = 16

∴ n = $\dfrac{16}{4}$

I.e n = 4

So, The number of items being purchased = n = 4

Hence, The number of items are being purchased is 4 . Answer
