#### A.3: demonstrate an understanding of the factors and methods involved in making and justifying informed purchasing decisions.

A.3.1: identify and describe various incentives in making purchasing decisions (e.g., 20% off; 1/3 off; buy 3 get 1 free; loyalty rewards; coupons; 0% financing)

A.3.2: estimate the sale price before taxes when making a purchase (e.g., estimate 25% off of \$38.99 as 25% or ΒΌ off of \$40, giving a discount of about \$10 and a sale price of approximately \$30; alternatively, estimate the same sale price as about 3/4 of \$40)

A.3.4: calculate discounts, sale prices, and after-tax costs, using technology

A.3.9: describe and compare, for different types of transactions, the extra costs that may be associated with making purchases (e.g., interest costs, exchange rates, shipping and handling costs, customs duty, insurance)

### B: Saving, Investing, and Borrowing

#### B.2: demonstrate an understanding of simple and compound interest, and solve problems involving related applications;

B.2.1: determine, through investigation using technology (e.g., calculator, spreadsheet), the effect on simple interest of changes in the principal, interest rate, or time, and solve problems involving applications of simple interest

B.2.2: determine, through investigation using technology, the compound interest for a given investment, using repeated calculations of simple interest for no more than 6 compounding periods

B.2.3: describe the relationship between simple interest and compound interest in various ways (i.e., orally; in writing; using tables and graphs)

B.2.4: determine, through investigation using technology (e.g., a TVM Solver in a graphing calculator or on a website), the effect on the future value of a compound interest investment of changing the total length of time, the interest rate, or the compounding period

B.2.5: solve problems, using technology, that involve applications of compound interest to saving and investing

#### B.3: interpret information about different ways of borrowing and their associated costs, and make and justify informed borrowing decisions.

B.3.1: gather, interpret, and compare information about the effects of carrying an outstanding balance on a credit card at current interest rates

B.3.3: calculate, using technology (e.g., calculator, spreadsheet), the total interest paid over the life of a personal loan, given the principal, the length of the loan, and the periodic payments, and use the calculations to justify the choice of a personal loan

### C: Transportation and Travel

#### C.2: plan and justify a route for a trip by automobile, and solve problems involving the associated costs;

C.2.1: determine distances represented on maps (e.g., provincial road map, local street map, Web-based maps), using given scales
