Question

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

The total cost of the trees including the delivery was $168.

How much did each tree cost?

Answer 1

$16.

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* \$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:

`(8t)/(8)=(128)/(8)`

`t=16`

Therefore, the cost of each tree is $16.
