Answer:
$16.
Step-by-step explanation:
Let t represent the cost of each tree.
We have been given that Yuri purchased 8 trees to have planted at his house. So the cost of 8 trees will be 8t.
We are also told that the store charged a delivery fee of $5 per tree. So the delivery charges of 8 trees will be [tex]8\times \$5=\$40[/tex]
The total cost of purchasing 8 trees will be [tex]8t+40[/tex].
Since the total cost of the trees including the delivery was $168, so we can get an equation as:
[tex]8t+40=168[/tex]
[tex]8t+40-40=168-40[/tex]
[tex]8t=128[/tex]
Upon dividing both sides of our given equation by 8, we will get:
[tex]\frac{8t}{8}=\frac{128}{8}[/tex]
[tex]t=16[/tex]
Therefore, the cost of each tree is $16.
