Jack earned twice as much as Mary and Jill earned $8 more than Mary. Who made the most money?

To determine who made the most money, we need to compare the amounts that Jack, Mary, and Jill earned.

1. We know that Jack earned twice as much as Mary. So, if Mary earned X dollars, Jack earned 2X dollars.

2. We also know that Jill earned $8 more than Mary. So, if Mary earned X dollars, Jill earned X +$8.

Without knowing the exact amount that Mary earned, we can't determine the exact amounts that Jack and Jill earned. However, we can determine who earned the most based on the information given.

Since Jack earned twice as much as Mary, and Jill only earned $8 more than Mary, Jack earned the most money.
