Darlene Fields is looking for a financial app that will help her manage her money and learn about saving ideas, investing, and portfolio allocation. She wants an app that is easy to use. She has compiled this table of data to help her decide which app to use. You can compute a score for each alternative by multiplying the importance rating for each attribute by the alternative's perceived rating on that attribute. Importance is on a scale from $1$ to $10$ with $10$ being best and Darlene's ratings are also on a scale from $1$ to $10$ with $10$ being best. These scores are then summed to determine the total composite score for each alternative. The highest composite score represents the best alternative.
