Ella spends 40% of the money she makes from babysitting on video games. Last year she spent $100. This year she received a 10% raise. What is Ella's new salary?
Thoughts? Step-by-step reasoning:
Last year Ella made a total of $100 / (40 / 100) = $250. This year with her raise, Ella's salary will be $250 * (110 / 100) = $275.
Thus, the answer is 275.
