Answer:
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
