To model this situation with a pair of linear equations, we first need to establish what the variables represent.

Let:

  • \( p \) be the number of members picking up litter.
  • \( c \) be the number of members cleaning the hallways.

There are two main equations we can derive from the problem description:

  1. The total number of members participating is 25, so: \[ p + c = 25 \]

  2. The total amount earned needs to be $300. Members earn $15 for picking up litter and $10 for cleaning hallways, so: \[ 15p + 10c = 300 \]

Thus, the correct pair of linear equations that models this situation is:

  1. \( p + c = 25 \)
  2. \( 15p + 10c = 300 \)

This corresponds to the option:

  • \( p+c=25 \); \( 15p+10c=300 \)

So, the response is: p plus c equals 25; 15 p plus 10 c equals 300.
