To find out how many tenth-graders are taking a foreign language other than German, we can look at the 10th grade row in the table:
- 10th graders taking French: 70
- 10th graders taking German: 64
- 10th graders taking Spanish: 44
Now, we need to calculate the total number of tenth graders taking a foreign language other than German. This includes those taking French and Spanish:
\[ \text{Total (other than German)} = \text{French} + \text{Spanish} = 70 + 44 = 114 \]
Therefore, 114 tenth-graders are taking a foreign language other than German.
