Video Learning Notes
Students learned to calculate simple and compound interest using formulas, compared the earnings from both types of interest, and analyzed monetary incentives such as sales, rebates, and coupons. They understood that compound interest generally yields more earnings over time because it earns interest on accumulated interest. They also practiced evaluating financial incentives to make informed consumer decisions.
Learning Goals
- Calculate simple interest earnings using the formula I = P × r × t.
- Calculate compound interest earnings using the formula A = P(1 + r)^t - P.
- Compare the total earnings from simple interest and compound interest for the same principal, rate, and time period.
- Analyze and compare monetary incentives including sales, rebates, and coupons to determine the best financial choice.
