Lucy earns money babysitting. Her earnings and hours worked represent a direct variation. She worked for 4 hours and earned $25.

SashulF [63]

For this case we have that by definition, a direct variation is given in the form:

$y = kx$

Where:

k: It is the constant of proportionality

According to the statement we have to:

$y = 25\\x = 4$

Substituting:

$25 = k4\\k = \frac {25} {4}$ $k = 6.25\ for\ \frac {dollars} {hour}$

On the other hand we have:

$y = 4\\x = 25\\4 = k25\\k = \frac {4} {25}$

$k = 0.16\ for\ \frac {hours} {dollar}$

Answer:

$k = 6.25 for \frac {dollars} {hour}\\k = 0.16 for \frac {hours} {dollar}$
