Question 760247
Your answer is correct. This is similar to problem number 760246.

I assume you solved it through 2 simultaneous equations. If the mix contains x pounds of trail mix and y pounds of cashews,

{{{ x + y = 105 }}}
{{{ 8*x + 15*y = 105*12 = 1260 }}}

Solving the above 2 equations, you get x = 45, y = 60.
