The amount of money y, that Valentina earns at her job after working x hours is given by t
He direct variation
Equation y=12.5x. Identify the constant of proportionality. What does the constant of proportionality represent?
A. The constant of proportionality is 1/12.5, and it represents the amount of money Valentina earns week at her job
B. The constant of proportionality is 1/12.5, and it represents the amount of money Valentina earns each hour at her job
C. The constant of proportionality is 12.5, and it represents the number of hours Valentina works each week at her job
D. The constant of proportionality is 12.5, and it represents Valentine's hourly wage
D. The constant of proportionality is 12.5, and it represents Valentine's hourly wage.
The constant of proportionality in the equation y = 12.5x is 12.5. Therefore, the correct answer is D. The constant of proportionality represents Valentina's hourly wage.
To identify the constant of proportionality, we can look at the equation y = 12.5x. In this equation, 12.5 is the coefficient of x, and it represents the constant of proportionality.
Now, let's look at the options provided:
A. The constant of proportionality is 1/12.5, and it represents the amount of money Valentina earns week at her job.
B. The constant of proportionality is 1/12.5, and it represents the amount of money Valentina earns each hour at her job.
C. The constant of proportionality is 12.5, and it represents the number of hours Valentina works each week at her job.
D. The constant of proportionality is 12.5, and it represents Valentina's hourly wage.
Based on the equation y = 12.5x, we can conclude that option D is correct. The constant of proportionality is 12.5, and it represents Valentina's hourly wage. This means that for every hour Valentina works, she earns $12.50.
