How long does it take to ring up a customer with 5 items?_____ seconds
Identify Variable Correspondence: Identify the variable that 5 items correspond to. p represents the number of items being purchased. So, 5 items gives the value for p.
Substitute Value for p: We know that p=5. Plug in the value for p in t=p+9. t=p+9 Substitute p with 5. t=5+9
Solve for t:t=5+9. Solve for t. t=p+9t=5+9=14
