First two (S = 9.20   K = 10.15)

Step-by-step explanation:

Hours = x

Money Earned (AED) = y

Shamael

y = 9.2x

AED = 9.2(hours)

$9.20 an hour

Kamla

y = kx

  ([tex]x_{1} ,y_{1}[/tex]) = (5, 50.75)

  ([tex]x_{2}, y_{2}[/tex]) = (4, 40.60)

  k = [tex]\frac{y_{1}-y_{2}}{x_{1}-x_{2}}[/tex] = [tex]\frac{50.75-40.60}{5-4}[/tex] = [tex]\frac{10.15}{1}[/tex] = 10.15

AED = 10.15(hours)

$10.15 an hour
