Answer:
Cost for each pound of jelly beans: $1.75
Cost for each pound of trail mix: $3.75
Explanation:
Define the variables:
- Let J be the cost of one pound of jelly beans.
- Let T be the cost of one pound of trail mix.
Using the given information and defined variables, create a system of equations:

To solve the system of equations, multiply the first equation by 3 to create a third equation:


Subtract the second equation from the third equation to eliminate the term in T:

Solve the equation for J by dividing both sides by 8:


Therefore, the cost of each pound of jelly beans is $1.75.
To find the cost of one pound of trail mix, substitute the found value of J into one of the original equations and solve for T.
Using the second equation:






Therefore, the cost of each pound of jelly beans is $3.75.
