Final answer:
The given situation where Nora has a minimum of $2 worth of nickels and dimes can be represented by the inequality $0.05n + $0.10d >= $2.
Step-by-step explanation:
Nora has n nickels and d dimes, and the value of the coins must be a minimum of $2. Since a nickel is worth $0.05 and a dime is worth $0.10, we can represent this situation as an inequality. The inequality will be $0.05n + $0.10d ≥ $2, where n is the number of nickels and d is the number of dimes.
