Answer: 64%
Step-by-step explanation:
The band needs $800 for new uniforms and of that, they only raised $512.
Set up a proportion 
and plug everything you know in.
= 
Solve for x by cross multiplying and dividing.
512 × 100 = 51200
51200 ÷ 800 = 64
x = 64
The school band has raised 64% of their goal already.
1. 2, 4, 8.
2. 2, 3, 5.
3. 2, 3, 5, 6, 8, 10.
That value is 60 because 15 is 1/4 of 60, and 25% is 1/4 of 100
The value of x is 8 when y = 12 if variables x and y have proportional relationship.
According to the given question.
Variables y and x have proportional relationship.
⇒ y ∝ x
Let k be the constant of proportionality.
⇒ y = kx
Also, it is given that
y = 21 when x = 14
Substitute the value of y = 21 and x = 14 in y = kx to find the value of k.
21 = k(14)
⇒ k = 21/14
⇒ k = 3/2
Therefore, the value of x when y = 12
y = kx
⇒ 12 = (3/2)x
⇒ 12 × 2 = 3x
⇒ 24 = 3x
⇒ x = 24/3
⇒ x = 8
Hence, the value of x is 8 when y = 12.
