12=k×4⇒k=3

Hence, the required equation is y=3x.

The value of y when x=5 is y=3x5=15.

sweet [91]

Answer:

$\$(4.65 + 0.55g)$

Step-by-step explanation:

Let the number of hundred CCF of gas consumed by the customer =g

$\text{When } 0 < g \leq 3\\ \text{Cost =} \$5\\\\\text{When } 3$

Therefore, when the hundred cubic feet, CCF of gas consumed is more than 9, the consumer pays for the first 9 and then pays for any subsequent CCF of gas at a rate of $0.55 per CCF

$\text{When g}>9 : \text{Cost =} 9.60+0.55(x-9)$

$=9.60+0.55g-4.95\\=\$(4.65 + 0.55g)$
