1. The problem asks to compare two chequing accounts from different Canadian banks based on monthly fees, free transactions, and extra charges to determine the better choice. 2. To compare, we use the formula for total monthly cost: $$\text{Total Cost} = \text{Monthly Fee} + (\text{Extra Transactions} \times \text{Fee per Extra Transaction})$$ 3. Suppose Bank A charges a monthly fee of 10 with 20 free transactions and 1.5 per extra transaction. Bank B charges 12 monthly fee with 30 free transactions and 1.25 per extra transaction. 4. If a user makes 25 transactions, Bank A's cost is $$10 + (25-20) \times 1.5 = 10 + 5 \times 1.5 = 10 + 7.5 = 17.5$$ 5. Bank B's cost is $$12 + (25-30) \times 1.25 = 12 + 0 = 12$$ since 25 is less than 30 free transactions. 6. Bank B is better because it has more free transactions and lower total cost for 25 transactions. 7. For frequent debit card use but little cash withdrawal, an account with more free debit transactions and low fees on debit purchases is best. Bank B suits this because it offers more free transactions. 8. Extra fees for exceeding free transactions can add up quickly, making accounts with low free transactions costly for heavy users. 9. For example, Bank A charges 1.5 per extra transaction, so 10 extra transactions cost 15, increasing monthly cost significantly. 10. Bank B charges less per extra transaction and offers more free transactions, reducing extra fees impact. Final answer: Bank B is the better choice due to more free transactions and lower extra fees, especially for users who use debit cards often but withdraw cash less.
