I don’t know what to do to get the constant of proportionality?

Step-by-step explanation:

Constant of proportionality- A proportional relationship that can be represented by the equation y=kx

k=Constant of proportionality

Equations: k=y/x or y=Kx

divide your y over your x

example: 2.50/1= 2.50

5.00/2=2.5

7.50/3= 2.5

10.00/4= 2.5

ιт ιѕ (9χ^5+10)(81χ^10-90χ^5+100)

step-by-step explanation:

нσρє ι ¢συℓ∂ нєℓρ уσυ συт тσ∂α

the answer is option a you would get more money.it would be $250.

step-by-step explanation:

for option b 200/2=100=50% 100/2=50=25% 50/5=10=5% it would be $220
