Is my 1st question a direct or inverse variation, and is My 2nd question a direct or inverse variation? Question: 1st Deku is saving up money so he can buy a limited time “All Might” poster. He saves $17 a week for 4 weeks. 2nd Shoto went out with his friends to the new “Cold Soba” restaurant. The total cost was $135.

  3. hard to say. If the number of friends can vary but the total cost remains the same, it's an inverse variation.

    Looks like you need to study the topic a bit more.
