Explanation:

Step1: Identify Union High's median

In a box - plot, the line inside the box represents the median. For Union High, the median is at 70.

Step2: Analyze Grant High's box - plot

In Grant High's box - plot, the box represents the inter - quartile range (25th to 75th percentile) and the line inside the box is the median. The right part of the box and the right whisker represent the data from the median to the maximum value.
We want to find the percentage of scores at Grant High that are greater than or equal to 70.
The median of Grant High is less than 70. The third - quartile (75th percentile) of Grant High is around 80.
The percentage of data greater than the third - quartile is 25%. And some data between the median and the third - quartile of Grant High is also greater than 70.
By observing the box - plot, we can see that approximately 50% of Grant High's scores are greater than or equal to 70.

Answer:

50%
