    Default Please help me understand Math problem

    6th Grade Math, MA6292 has a question regarding Frankita creating 15 pictures in 15 minutes, 17 pictures in 30 minutes, 20 pictures in 45 minutes, 24 pictures in 60 minutes. Does it not stand to reason that, since the number of drawings she has increased in increments of 1, 2, 3, and 4, then at 75 minutes it will increase by 5 to 29 pictures; and at 90 minutes it will increase by 6 to 35 pictures?

    The answer key states that at 90 minutes she will draw 140 pictures, and I don't understand how that works.

    Ok, we didn't understand the question. They want to total number of drawings after 90 minutes, not how many drawings she was able to do make in 90 minutes. Tricky question.
