Answer 1

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:
\[
3t + 2g = 51
\]
