Question

this graph shows how the time required to ring up a customer is related to the number of items being purchased. how long does it take to ring up a customer with 4 items?

Explanation:

Step1: Locate the number of items on the y - axis

Find the value \(4\) on the y - axis (Items being purchased).

Step2: Trace horizontally to the line and then vertically to the x - axis

From \(y = 4\), move horizontally until you hit the line graph. Then move vertically down to the x - axis (Time). The x - value at this point is \(70\).

Answer:

\(70\) seconds
