The total number t of items that a manufacturing company can produce is directly proportional to the number n of employees. (a) Write an equation that shows the proportionality relation. (Let k be the constant of proportionality.)    What in practical terms does the constant of proportionality represent in this case?

Solve the problem using the relationship between brightness B, luminosity L, and distance d. The proportionality constant is k = 0.080.
