1 answer

To represent the total weight of the trail mix and granola, you can use the following equation:

\[ t + g = 21 \]

Where:

  • \( t \) represents the number of pounds of trail mix.
  • \( g \) represents the number of pounds of granola.

In addition, you've provided another equation related to the costs:

\[ 3t + 2g = 51 \]

This equation represents the total cost based on the price per pound of trail mix and granola.

In summary, you have two equations:

  1. For the total weight: \[ t + g = 21 \]

  2. For the total cost: \[ 3t + 2g = 51 \]
