Skylar has nn nickels and dd dimes. She has at most 21 coins altogether. Write this situation as an inequality.

1 answer

To express the situation with Skylar's coins as an inequality, we need to consider the total number of coins she has, which consists of \( n \) nickels and \( d \) dimes. According to the problem, the total number of coins is at most 21. This can be written as:

\[ n + d \leq 21 \]

Here:

  • \( n \) represents the number of nickels.
  • \( d \) represents the number of dimes.

Thus, the inequality \( n + d \leq 21 \) accurately captures the given situation.
