4 products are being purchased.
Step-by-step explanation:
Given,
Time taken to select each product = 5 seconds
Time taken to complete check out process = 60 seconds
Total time taken for a transaction = 80 seconds
Let,
x be the number of products purchased.
Time taken for each product*Number of product + Time for check out process = total process
[tex]5x+60=80\\5x=80-60\\5x=20[/tex]
Dividing both sides by 5
[tex]\frac{5x}{5}=\frac{20}{5}\\x=4[/tex]
4 products are being purchased.
