N4 · Compare services used to access and manage finances

Alberta Grade 11 Mathematics

Number and money

Choose services by comparing access, features, cost, and fit

What you will learn

• Describe ways people access and manage money.
• Compare services using the same needs and cost period.
• Calculate and explain a simple service cost using clearly stated hypothetical fees.
• Choose a service that fits a person's situation and explain the choice.

1. Start with the person's needs

• Name the tasks the person needs to do before choosing a service.
• Compare access, features, costs, and convenience.
• Check service details rather than assuming every provider offers the same features.

2. Compare costs on the same basis

• Use the same time period and transaction pattern for each option.
• Include only the fees and allowances given in the service information.
• A lower calculated cost does not automatically mean a better fit.

3. Compare features and access

• Separate known features from details that still need checking.
• Consider access and practical limits as well as fees.
• Explain why the chosen service fits the person's priorities.

4. Make and explain a choice

• Base the decision on the information provided and the person's needs.
• State assumptions and missing details clearly.
• Check the period, transaction count, and currency in the final comparison.

A comparison checklist

Worked example

Compare two hypothetical monthly service options

1. Use the same pattern
   Both options are compared for one month and four withdrawals. These hypothetical charges are supplied only for this example; they are not current provider fees.
2. Calculate Option A
   Add its monthly charge to four withdrawal charges. The units match: each withdrawal charge is counted once for each withdrawal.
   $$3+1\times4=7$$
3. Compare and interpret
   Option B costs CAD 6 under the stated pattern. Option A costs CAD 7, so Option B costs CAD 1 less for this month's four withdrawals. This does not establish which option is best for other uses or months.
   $$7-6=1$$

Worked example

Compare features as well as cost

1. Identify priorities
   The person wants mobile balance checks and sometimes needs help from staff. Both descriptions include app balance checks, so that feature does not distinguish these choices.
2. Compare the remaining features and stated costs
   Service Y lists a nearby branch, while Service X does not. Service Y's stated monthly charge is CAD 3 higher. The descriptions do not provide enough information to assume that either service has no other fees.
   $$5-2=3$$
3. Make a choice using the person's priorities
   If in-person help is important, Service Y is the better fit based on the supplied description, despite its higher stated monthly charge. Before choosing, the person should check for other fees and confirm the branch's services and hours.

Worked example

Check a yearly cost from a monthly charge

1. Confirm the assumption
   The example states that the monthly charge stays the same for all 12 months and that there are no other charges. These are hypothetical conditions for the calculation.
2. Multiply by the number of months
   There are 12 months in the year. Count the same CAD 4 charge once for each month.
   $$4\times12=48$$
3. State the result with its period
   The total is CAD 48 for one year under the stated assumptions. If the charge or terms changed, the actual yearly total could be different.

Common mistakes and how to avoid them

• Compare access, features, and fees using the same time period and usage assumptions.
• Use only stated information; identify details that need checking.
