Answer: 20%
Step-by-step explanation:
The 150 students in the marching band and 30 of the students play the trumpet. To get the percentage of students that play the trumpet, we divide 30 by 150 and then multiply by 100. This can be written as:
= 30/150 × 100
= 0.2 × 100
= 20%
The percentage of students that play the trumpet is 20%

X = apples trees
Y= azaleas
6x + 5y = 219
3x + 4y = 132
-2(3x + 4y = 132)
-6x - 8y = -264
6x + 5y = 219
-3y = -45
-3y/-3 = -45/-3
y = 15
6x + 5y = 219
6x + 5(15) = 219
6x + 75 - 75 = 219 - 75
6x/6 = 144/6
X = 24
The cost for each apple tree is $24 and fit each azalea is $15
