You would first add the two parts of the ratio to get ten, then divide 120 by ten to get 12. This means that each part of the ratio is worth 12 dollars, so to get the helper’s salary you would multiply 12 by three to get a total of 36.
Answer:
1.08 is the constant of proportionality.
Step-by-step explanation:
The constant value (often written k) relating amounts that rise or fall uniformly together.
It is the ratio of the amounts y and x:
k = y/x
Put another way: y = kx
Example: you are paid $20 an hour
The constant of proportionality is 20 because: Pay = 20 × Hours worked
