Final answer:
To find the unit cost of each apple tree and azalea, set up a system of equations using the given information and then solve.
Step-by-step explanation:
To find the unit cost for each apple tree and each azalea, we can set up a system of equations. Let's use x to represent the unit cost of an apple tree and y to represent the unit cost of an azalea.
The first equation using the given information is: 6x + 5y = 147.
The second equation is: 3x + 4y = 96.
We can solve this system of equations using the method of substitution or elimination to find the values of x and y.
