A student conducted an experiment to find out if air temperature affected the total number of seeds that germinate.  Two groups of 100 identical seeds were used.  One group was kept at an air temperature of 10°C and the other at an air temperature of 20°C.  All other conditions were held constant.  Observations made during the experiment are shown in the data table below.

Using the graph below, determine how many seeds would have germinated at 10°C by day 12. (write the number only)
