VIDEO of lesson: Notes: see e-newspaper Practice: Do “The best place to stash the cash” – Do Scenario 1 or 2 W Jun 17 Finance: Borrowing It Questions from last class? VIDEO of lesson: Notes: see e-newspaper Practice: Use https://www.mycalculators.com/ca/loancalcm.html to do the following problem. You charge a \$2500 bike on your credit card (including taxes). The card has an annual interest rate of 19% that compounds monthly. You plan to pay \$110 per month to the credit card company. Fill in these three values on the website above, then click on the “Months” button. How long will it take you to pay for the bike? How much will you pay in total over the life of this loan? If you change the interest rate to 6%, as you might get for a bank loan, what is the new time to pay for the bike and new total paid? Now, increase your payment to \$200 per month. What does that do to the length of time and total paid? (try this for both 6%, then 19%) What gives you the shortest length of time and least total paid for a \$2500 loan? Answers in order: 28.39 months, \$3123.56; 24.19 months, \$2660.48; 12.94 months, \$2588.02, 14.04 months, \$2807.84; lowest interest rate and highest monthly payment Have a great summer!!
