A nursery has two hundred 7-gallon palm trees to sell, consisting of Coconut Palm trees, x, Saw Palmetto Palm trees, y, and Christmas Palm trees, z. Coconut Palm trees sell for $75 each, Saw Palmetto Palm trees sell for $45 each, and Christmas Palm trees sell for $30 each. A developer purchases all of the nursery's palm trees for a total

price of $12,300. The nursery has three times as many Saw Palmetto Palm trees as Christmas Palm trees. Write a system of linear equations to represent this situation.

A 2+y+z=7

75x + 45y + 30z = 12,300

y = 32

B. x+y+z= 12,300

75x + 45y + 30z = 200

y = 32

C. 2 + y + z = 200

752 + 45y + 30z = 12,300

y = 32

D. 2+y+z= 200

753 + 45y + 30z = 12,300

z=3y
