Start the 30 questions Curriculum: G8-F1.6

Sample: the first question, solved

Compare Card A (no annual fee, 18% interest) to Card B ($95 fee, 14% interest), for someone who always pays their balance in full. Which is better?

📘 Worked solution
Card A - since interest doesn't matter if the balance is always paid in full, the only cost difference is the annual fee, which Card A lacks.

And one from the hard end

Compare 3 cards for someone carrying a $1200 balance all year with $10000/year in spending: Card A (no fee, 19% interest, 1% cash back), Card B ($75 fee, 13% interest, 2% cash back), Card C ($150 fee, 9% interest, 3.5% cash back). Card C is the only one whose cash back exceeds its interest plus fee - find the size of that net annual gain.
