Question

Yuri purchased 8 trees to have planted at his house. The store charged a delivery fee of $5 per tree.

Answer 1

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 $8\times \ 5=\ 40$

The total cost of purchasing 8 trees will be $8t+40$.  

Since the total cost of the trees including the delivery was $168, so we can get an equation as:

$8t+40=168$

$8t+40-40=168-40$

$8t=128$

Upon dividing both sides of our given equation by 8, we will get:

$\frac{8t}{8}=\frac{128}{8}$  

$t=16$  

Therefore, the cost of each tree is $16.
