The constant of proportionality is the ratio between the two proportional variables in a directly proportional relationship. In this case, the variables are and .
To find the constant of proportionality, all we have to do is divide any value of by its corresponding value of . Let's take the values in the first row of the table. We know that and , so the constant of proportionality is . Hope this helps!
$6 x the number of hours he works + $7.50 times the number of hours he works has to be less than or equal to (≤) 15 hours. The number of hours he works has to be more than or equal (≥) to $75. Great job choosing the correct answer!
