Q. This equation shows how the time required to ring up a customer is related to the number of items being purchased.\newlinet=p+9t = p + 9\newlineThe variable pp represents the number of items being purchased, and the variable tt represents the time required to ring up the customer. How long does it take to ring up a customer with 55 items?\newline_____ seconds
  1. Identify Variable Correspondence: Identify the variable that 55 items correspond to. pp represents the number of items being purchased. So, 55 items gives the value for pp.
  2. Substitute Value for pp: We know that p=5p = 5. Plug in the value for pp in t=p+9t = p + 9. t=p+9t = p + 9 Substitute pp with 55. t=5+9t = 5 + 9
  3. Solve for t: t=5+9t = 5 + 9. Solve for tt. t=p+9t = p + 9 t=5+9=14t = 5 + 9 = 14
