This equation shows how the time required to ring up a customer is related to the number of items being purchased. t = 4p + 20 T
konstantin123 [22]

Answer:

6 items are being purchased

Step-by-step explanation:

Given that  variable p represents the number of items being purchased, and the variable t represents the time required to ring up the customer, If it takes 44 seconds to ring up a customer then the number of items being purchased may be computed by substituting the value of t into the given equation

t = 4p + 20.

Using t = 44

44 = 4p + 20

collect like terms or subtract 20 from both sides

44 - 20 = 4p

24 = 4p

Divide both sides by 4

24/4 = p

p = 6
