It contains twice as much peanuts by weight as apricots.

One pound of dried apricots costs $4.48

One pound of raisins cost  $2.40.

One pound of peanuts cost $3.44.

To calculate cost of one pound mixture, we will multiply the amount of each ingredients present in one pound mixture with their respective costs:

One pound of dried apricots costs = $4.48

of dried apricots costs =

One pound of peanuts cost = $3.44.

of peanuts cost =

One pound of raisins cost = $2.40.

of raisins cost =

One pound mixture contains apricots = =

Now, convert it into ounces;

1 pound = 16 ounces

=

One pound mixture contains peanuts  =

one pound mixture contains raisins =

Therefore, 1 pound of the trail mix contains 3 ounces of apricots, 6 ounces of peanuts and 7 ounces of raisins.
