c. 4
d. 33

Explanation:

Step1: Locate 7.5 on x - axis

Estimate position between 7 and 8.

Step2: Draw vertical line from 7.5

Draw line up to the curve.

Step3: Draw horizontal line from intersection

Draw line to y - axis to read value.
By visual inspection of the graph, the value on the y - axis (cumulative number of baskets) corresponding to 7.5 minutes is close to 29.
