This EDITABLE worksheet includes a short explanation of simple interest, the formula with what each variable means and four word problems. The problems ask students to solve for rate, time and principal. Also included is a bonus problem that asks students to create their own simple interest problem. For fun, students may notice a common theme in the names used (from Harry Potter).
If you like this resource, please take a look at Simple Interest I (free) which contains basic simple interest problems where students solve only for the interest.
