To find out how many slices of mango are needed for 10 cups of yogurt, we can look at the trend in the graph.
If we follow the pattern of the plotted points, we can see that for every 2 cups of yogurt, there are 16 slices of mango. Therefore, for 10 cups of yogurt, we would need 10/2 = 5 sets of 2 cups yogurt (which equals 10 cups of yogurt).
So, for 10 cups of yogurt, we would need 5 sets * 16 slices = 80 slices of mango.
Therefore, 80 slices of mango are needed for 10 cups of yogurt.
