sry if my answer is wrong but I think it is the square root of nine
Well, we know that 25% is also 1/4 and if we multiply $80.00 by 1/4 you get $20 so the answer is $20.
Answer:
The answer is D) 60
Step-by-step explanation:
Given:
y is proportional to x.
y=10 and x=8.
To find:
The constant of proportionality and the equation for the proportional relationship.
Solution:
y is proportional to x.

...(i)
Where, k is the constant of proportionality.
Putting y=10 and x=8, we get



Putting
in (i), we get

Therefore, the contestant of proportionality is
and the equation for the proportional relationship is
.
