Your experience with travelling tells you how to figure this out: That is, Notice that you don't have to rely on just your memory to recall this formula. She runs full speed at 8 miles per hour for the race distance; then she walks back to her starting point at 2 miles per hour. Set the distances equal and solve for x: She spends 0.4 hours running and hours walking. One account pays interest, while the other pays interest. Since a total of 00 was invested, must have been invested at . After one interest period, the interest earned on a 00 investment exceeds the interest earned on a 00 investment by 0.

What would be the x-intercept, and what can she learn from it?

To answer these and related questions, we can create a model using a linear function.

The interest earned on the 00 investment is , and the interest earned on the 00 investment is .

The interest earned on a 00 investment exceeds the interest earned on a 00 investment by 0, so The interest rates were for the 00 investment and for the 00 investment.
