Answer:

Zicrons

Explanation:

The owner of a tree farm decides to harvest a stand of mature white pine trees. Each white pine yields approximately 62 board fe
adelina 88 [10]

Answer:

$13764 ; $247752 ; $173426 ; $259740

Explanation:

1 white pine = 62 board feets

Density of white pine = 120 trees per acre

Wholesale price per board foot = $1.85

The value per acre of white pines

(Number of board foots per white pine) * (Number of white pines per acre) * (wholesale price per board foot)

(62 * 120 * $1.85) = $13,764

B.) Amount Realized on harvesting 18 acres

Value per acre * 18

$13764 * 18

= $247752

C.)

Amount charged by timber company = 30% of wholesale price

Total wholesale amount realized on 18 acre = $247752

Amount left after paying timber company :

$247752 - (0.3 * $247752)

= $173426.4

= $173426 (nearest dollar)

d.

Amount made now : = $247752

After 10 years :

The value per acre of white pines

(Number of board foots per white pine) * (Number of white pines per acre) * (wholesale price per board foot)

(127 * 120 * $1.85 * 18) = $507492

$507492 - $247752 = $259740
