Answer:  \bold{a)\quad E=\dfrac{1}{5}s}

                b) 75

                c) $24

<u>Step-by-step explanation:</u>

the difference in the y-values (electricity) divided by the difference in the x-values (students) is the rate of change. \dfrac{10}{50}=\large\boxed{\dfrac{1}{5}}

Electricity = rate of change × students  ⇒   E=\dfrac{1}{5}s

b) Find s when E = 15  

   15=\dfrac{1}{5}s\\\\\\(5)15=(5)\dfrac{1}{5}s\\\\\\\large\boxed{75 = s}

c) Find E when s = 120

   E=\dfrac{1}{5}\times 120\\\\\\E=\dfrac{120}{5}\\\\\\\large\boxed{E=24}
